Track down the causes of QEMU crashes seen under OBS
Martin Mohring reports that using qemu-linaro to do Meego builds in OBS reveals some persistent crash issues. I had thought that this was caused by TCG's locking issues with multithreaded linux-user apps. However Martin tested a patch by me which I believe fixes those locking problems and still saw crashes.
This sort of cross-build assist is a really popular use of QEMU so we should devote time to fixing these issues, since we should be able to get usefully reproducible test cases.

Whiteboard
This blueprint is blocked for now as we don't have any test cases or problem information. I assume "no news is good news" or at least an indication that the problems aren't too serious.
