TestExecuteNoWait waiting a long time...

Anyone seeing the same as I do?

Support/SupportTests/ProgramTest.TestExecuteNoWait takes many seconds,
and since it normally runs at the end, it's adding those seconds of
wait to the whole test run. This is a debug run with shared libraries
built in.

I had a peek into the code and there's nothing obvious as to why it
would wait that long...
