* 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...
