From cdd090b11e14b7e1b33a3f836809093ffa99209b Mon Sep 17 00:00:00 2001 From: Mike Bayer Date: Tue, 9 Jan 2018 23:35:23 -0500 Subject: [PATCH] Disable the singletonthreadpool test cleanup no gc This test often fails on CI under load and reveals a small race condition within SingleonThreadPool's "cleanup" system. As this pool's "cleanup" system is pretty much never used in any case since this pool is no longer used for SQLite file databases, this race should have little impact, especially since the occasional non-closed connection will get closed out when it's GC'ed in any case.
