/* Bobbin: A library to aid debugging/performance tuning of threads.
 *
 * Usage (with C):
 *    First, build your project with BOBBIN defined, and include this
 *    header file wherever you use threading functions.
 *    This header file will use macros to point threading functions to
 *    Bobbin equivalents.
 *
 *    Run your program, and all threading functions should be redirected
 *    through here. When the program exits, you will get an interesting
 *    list of facts.
