Re: lib/52007: New failures in lib/libevent/t_event test

OK, done.

This is insufficient to close this PR, we still need to find out why
the test fails in those circumstances where it should succeed.

And it wouldn't hurt to do as Christos suggested, and make the test
just skip if the environment is not suitable (if we can work out how
to determine that properly, and accurately.)   Even with that, this
test is so slow that it probably shouldn't be run by default (perhaps
someday ATF/Kyua could be made able to have test modes of operation,
and this one would be included in the "run everything" mode, but not
the "run everytime" mode...)
