Summary0000422: Intermittent runtime aborts in parallel conjunction tests
DescriptionVarious tests in tests/par_conj intermittently abort on my system with:

     Mercury runtime: Unable to init shared engine thread.

For example, with the spawn_many test case, about half the invocations correct and the other
half abort with the above message.

This is occurring in the grade none.par.gc.stseg.ll_debug.
Additional InformationThe C compiler on my system is:

Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
