The system done at Purdue which Don Libes mentioned is called ConcurrenC,
which is our port of Xinu within a single Unix process.  We kept Xinu
functionality in tact, with some name changes of system calls due to conflicts
with Unix systems calls.  We also kept Unix semantics and functionality as much
as possible.  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.

The following gives information on how to obtain ConcurrenC.  Note that a
copy of your Unix source licence is required.
