I ran the test suite yesterday and when I came back this morning the queue_user_work_item.cc test was hung. This could be why the sanitizer-windows buildbot keeps randomly timing out. I updated all the usages of WaitForSingleObject involving threading events. I'm assuming the API can reliably wait for subprocesses, which is what the majority of call sites use it for. While I'm at it, we can simplify some EH tests now that clang can compile C++ EH. llvm-svn: 261338
