Hi Mike,
Have you ever thought of using the UNIX select function to implement a
"delay that doesn't burn CPU cycles or issue s shell command?
All you need to do is set all three of the file descriptor mask addresses
to null addresses, and point to a timeval structure initialized with the
desired delay time, and the UNIX kernel will swap you out until the time
has expired. Works like a champ!
