That PR doesn't contain details (how many CPUs did the machines have, was it
parallel make check and with what -jN), so hard to guess.
The patch certainly doesn't try to parallelize libgomp testsuite (i.e. run
more than one libgomp test at the same time).
I'll see how much does it help in real-world testing later tonight.
All I can say from my logs is that on a quiet machine the patched libgomp
make check-target-libgomp -j2 took 648s,
make check-target-libgomp took 618s.
Last night (nonpatched libgomp) and make -j32 -k check of everything
libgomp took 1912s. And two days ago, concurrent x86_64-linux and i686-linux
make -j32 -k check of everything libgomp took 2626s (x86_64) and 3300s (i686).
All times are wall clock in between the timestamps at the beginning and end
of testsuite/libgomp.log.
