[Qemu-devel] [Bug 1350435] Re: tcg.c:1693: tcg fatal error

[Peter Maydell]

That patch is not in mainline because it's an appalling hack. If we care
about multi-threaded guests we need to fix them properly, not paper over
the issues by constraining multiple threads to one CPU in the hopes the
race conditions don't bite us so often.
