Track down the causes of QEMU crashes seen under OBS

Registered by Peter Maydell on 2011-05-26

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.
