setnumcapabilities001 sometimes fails on Windows
I have seen the setnumcapabilities001
test fail at least once on Windows ([https://phabricator.haskell.org/harbormaster/build/14178/?l=0]). It seems that the assertion ASSERT(n_idle == 0);
in Schedule.scheduleDoGC
is to blame in this particular case,
setnumcapabilities001.exe: internal error: ASSERTION FAILED: file rts\Schedule.c, line 1636
