It builds fine on x86 Linux with a few minor changes:
        1) Use forward slashes instead of backslashes when including headers.
Windows will support #include <boost/header.hpp>, but not all Unix systems
(Linux included) support #include <boost\header.hpp>.
        2) xlock.hpp has an extra "typename" in line 61 that GCC complains about.

However, I have reproduced the deadlock problem with the example program.

A compiler at GCC's highest warning level (-ansi -pedantic -Wall) results in
some signed/unsigned comparison warnings in the pthread handling code.
Commonly the condition:

if (milliseconds == -1)

appears, where "milliseconds" is an unsigned int. Is this safe/intended?
