This directory contains a test of barriers. It's identical to
../Barrier-cpu, but uses the SingleSimMux class rather than the
SingleCpuMux class, and, in part, is used to compare relative
performance of the time-ordered queues (SimMux) and the unordered
queues(CpuMux).

On Foobar, a DECstation-3100 this test takes:
       35.0 real        31.1 user         1.7 sys
