Nice.

My platform doesn't have a <sys/time.h>. I suspect it should be
protected by an #ifdef ITIMER_REAL.

My platform (Win32) doesn't have SIGALRM either. This hunk should
probably be protected by #ifndef NEED_CALIBRATE or similar.

Also, "inline" is a C99ism. Should that read _X_INLINE to support C89
compilers?
