+ * 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).

+ * return the number of sent bytes instead of an error because pread()
+ * is, in theory, idempotent. However, special files in /dev or /proc

+ * relative or absolute).
+ *
+ * - If there's really only a filename, check the current directory for file,

+ * - If filename specified has *any* extension, search for the file with the
+ * specified extension first.

+ * - If the literal filename is not found in a directory, try *appending*

+ *
+ * - The path variable may contain relative paths; relative paths are relative
+ * to the cwd.
+ *
+ * - Directories in path may or may not end with a trailing backslash.
+ *
+ * - CMD does not trim leading/trailing whitespace from path/pathex entries
+ * nor from the environment variables as a whole.
+ *
+ * - When cmd.exe cannot read a directory, it will just skip it and go on
+ * searching. However, unlike posix-y systems, it will happily try to run a
+ * file that is not readable/executable; if the spawn fails it will not
+ * continue searching.
+ *
+ * UNC path support: we are dealing with UNC paths in both the path and the
+ * filename. This is a deviation from what cmd.exe does (it does not let you
+ * start a program by specifying an UNC path on the command line) but this is

+ * of the caret when the first stdout/err handle is created, unless that would
+ * mean that it would extend beyond the bottom of the screen buffer - in that
+ * that case it's located as far down as possible.
