Subject: [Boost-build] JAM_SEMAPHORE documentation?

Hi Builders,
Is there documentation on JAM_SEMAPHORE ? I see examples; but google did not reveal any documentation.
I'm trying to find way to help the build team speed up our nightly builds?

I retained a semaphore on the link when I created clang-vxworks.jam
but I question if it is really required anymore?

I'd also like to serialize test execution
For VxWorks we telnet and execute the test on a remote target board using a "launcher"

For the simulated and smaller arm targets, we need to ensure only one telnet session is active, or the test target runs out of memory.
(We are cross-compiling on big servers, so the build can be many-threaded, but the target is an embedded target and may be quite resource constrained )

How can I add a semaphore on "run" and "run-fail" rules that only gets applied to target-os=vxworks ?
