As suggested on IRC, I ran a proposed omp testcase (in
LP:668799) in a armel chroot created by the same
patched qemu-arm-static, with 6 and 60 threads, and
tried running a few java binaries I've found -- that
works well from creating system to building and running
testcases.  I also tried the same with qemu-system-i386
(without kvm), installing a system using patched qemu,
and running multi-threaded apps in it.

At least I don't see any obvious new breakages due to
my backport, but I can definitely go further than with
unpatched qemu.

So this is at least promising, so far... ;)

Thanks,
