Subject: Dispose more carefully of connections and threads in concurrency tests
X-Git-Tag: 3.0.4~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=75544572069696aaf031cae83fa7271253faf3a0;p=thirdparty%2Fpsycopg.git

Dispose more carefully of connections and threads in concurrency tests

I have seen some segfault on Windows sometimes, probably with the
test_concurrency thread stomping over the memory of the process forked
in test_multiprocess_close.

Async tests refactored the same way, although they don't exhibit the
same problem.
