I suspect http://trac.webkit.org/changeset/184846 https://build.webkit.org/builders/Apple%20Yosemite%20Debug%20WK1%20%28Tests%29/builds/5237/steps/run-api-tests/logs/stdio PASS WKUserContentController.ScriptMessageHandlerBasicPost PASS WKUserContentController.ScriptMessageHandlerBasicRemove PASS WKUserContentController.ScriptMessageHandlerCallRemovedHandler TIMEOUT WKUserContentController.ScriptMessageHandlerWithNavigation 1100714 1 sam 2015-06-09 11:15:35 -0700 Is there anyway to get a spindump or sample when the timeout is happening? 1100749 2 ap 2015-06-09 12:34:51 -0700 I can't think of any way to get a spindump, no. FWIW, this timeout kicks in very quickly - test runs where it occurs are only 7-8 seconds longer than those where it doesn't.
