 * ldap_pvt_thread_sleep.c - allow a thread to sleep without putting
 * the whole process (e.g. pod under lwp) to sleep.
 *
 * Contains platform-specific code to allow this:
 *
 * Under non-preemptive threads packages like SunOS lwp, tsleep() adds
 * the thread to a list of sleepers.  The lwp_scheduler process takes
 * care of resuming suspended threads.
 *
 * Under a fully-preemptive threads package, like Solaris threads,
 * tsleep just calls sleep(), and there is no scheduler thread.  Life
 * is so much simpler...
