See other discussion.  Performance should be identical, after
the upcall is eliminated in the case where all threads are
created PTHREAD_SCOPE_SYSTEM, and libkse communicates this to
the kernel to avoid generation of upcalls on blocking operations.

Jeff makes a good point about the potential for bugs because of
the more sophisticated and larger total number of lines of code,
however.

Daniel also makes a good point about not finding them unless the
code is put in production.

To my mind, it comes down to bug avoidance vs. bug detection, if
you weigh these arguments against each other.
