ConcurrenC is preemptive thread package for UNIX based on Xinu.  It is
not entirely portable, but it is as close as possible.

Here is the relevant stuff from a posting by Ken Rodemann in comp.os.xinu:

   ...Unix C library routines are made mutual exclusive, and a
   blocking I/O ConcurrenC task does not block other tasks in the
   system.  The ConcurrenC system includes src for the Xinu/ConcurrenC
   routines, source for modified Unix C library routines, and manual
   pages which list the Xinu name changes within ConcurrenC,
   restricted Unix system calls, etc.

I suggest you read/write the xinu-info@purdue.edu mailing list for
more info.
