There is a VxWorks implementation of the Posix threads API, they call it
pthreadLib and it claims to be "an implementation of POSIX 1003.1c
threads for VxWorks". EPICS doesn't use it because our VxWorks code
pre-dated that library, we had been using the native real-time APIs for
a long time before it came out.

I guess that might be an interesting path for replacing the UP (single
CPU) OS-dependent interface that we currently have for VxWorks for
anyone who wants to use an SMP version of VxWorks.
