- * 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...
