+ * This file defines data structures for different types of trees:
+ * splay trees and red-black trees.
+ *
+ * A splay tree is a self-organizing data structure.  Every operation
+ * on the tree causes a splay to happen.  The splay moves the requested
+ * node to the root of the tree and partly rebalances it.
+ *
+ * This has the benefit that request locality causes faster lookups as
+ * the requested nodes move to the top of the tree.  On the other hand,
+ * every lookup causes memory writes.
+ *
+ * The Balance Theorem bounds the total access time for m operations
+ * and n inserts on an initially empty tree as O((m + n)lg n).  The
+ * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
+ *
+ * A red-black tree is a binary search tree with the node color as an
+ * extra attribute.  It fulfills a set of conditions:
+ *  - every search path from the root to a leaf consists of the
+ *    same number of black nodes,
+ *  - each red node (except for the root) has a black parent,
+ *  - each leaf node is black.
+ *
+ * Every operation on a red-black tree is bounded as O(lg n).
+ * The maximum height of a red-black tree is 2lg (n+1).

+ * UNIX signal handling on a per-event loop basis. The implementation is not

+ * NPTL pthreads library to manage threads. Installing watchers for those
+ * signals will lead to unpredictable behavior and is strongly discouraged.
+ * Future versions of libuv may simply reject them.
+ *
+ * Some signal support is available on Windows:
+ *
+ *   SIGINT is normally delivered when the user presses CTRL+C. However, like
+ *   on Unix, it is not generated when terminal raw mode is enabled.
+ *
+ *   SIGBREAK is delivered when the user pressed CTRL+BREAK.
+ *
+ *   SIGHUP is generated when the user closes the console window. On SIGHUP the
+ *   program is given approximately 10 seconds to perform cleanup. After that
+ *   Windows will unconditionally terminate it.
+ *
+ *   SIGWINCH is raised whenever libuv detects that the console has been
+ *   resized. SIGWINCH is emulated by libuv when the program uses an uv_tty_t
+ *   handle to write to the console. SIGWINCH may not always be delivered in a
+ *   timely manner; libuv will only detect size changes when the cursor is
+ *   being moved. When a readable uv_tty_handle is used in raw mode, resizing
+ *   the console buffer will also trigger a SIGWINCH signal.
+ *
+ * Watchers for other signals can be successfully created, but these signals
+ * are never generated. These signals are: SIGILL, SIGABRT, SIGFPE, SIGSEGV,
+ * SIGTERM and SIGKILL.
+ *
+ * Note that calls to raise() or abort() to programmatically raise a signal are
+ * not detected by libuv; these will not trigger a signal watcher.
