[WinCairo] Dead lock in WTF::Thread::didExit() while WebKitNetworkProcess.exe is exiting

By running run-webkit-tests, sometimes WebKitNetworkProcess.exe process doesn't exit.

> python ./Tools/Scripts/run-webkit-tests --wincairo --debug --no-new-test-results --no-retry-failures --no-show-results -f fast

I don't know when this issue started to happen, but not so long time ago.
I fixed very similar issue in 5 months ago.
