Err, I'm not sure what effect that will have in Anthony's patchbut it probably wouldn't be good. As I say I haven't managed to reproduce this other than in a full qemu-dm tree (from qemu-xen). So it may be that it is because of something I did or something the qemu-xen code does - although it seems hard to imagine how it could break the signal mask in the helper thread given that that thread runs entirely glibc code, except when a signal is being delivered (and of course the signal mask is saved and restored for signal delivery). Perhaps the signal is being consumed in one of qemu-dm's other threads mistakenly? What you're describing would seem like a serious bug. For a while, I was testing a version of QEMU/KVM that slept forever in select() and I never saw any instances of the signal not getting delivered.
