Thanks for pointing that out. Also, the other patch in this series also seems to be unnecessary now. - Cleber. > thanks > -- PMM >

Also, are these the g_test_quick tests, or the other ones? It it's just a matter of the program taking too long to run, we could just reduce the length of the !quick tests (currently at 5s vs. 1s for the quick ones). Thanks, Emilio

Does this test still get stuck in builds after a458774ad711bceabefb ? That fixed an OSX-specific problem that caused hangs (notably in test-bdrv-drain, but it could I guess also affect other tests). thanks -- PMM
[Qemu-devel] [RFC PATCH 1/2] tests/test-qht-par: test gets stuck intermittently on OSX
To be fully honest, this may not be a OSX (alone) condition, but may be a situation that only happens with OSX on Travis-CI, were resources are quite limited. I have personal experience with tests that exercise parallelism or depend on timing to fail on Travis. Because I'm not 100% certain that this is a situation that only happens with OSX on Travis-CI, and because I'm not certain that we should be skipping tests because they're running on Travis-CI, let's disable them on OSX as a whole. A small note: this type of change makes me believe that there should be a list of testing related caveats or TODO list tracked on the documentation.
