Comment 16 for bug 955379

> this blocks forever, because the thing that would wake it up is the signal handler writing to the pipe we're selecting on, but we will never run the signal handler until select exits

Duh, makes sense, have to think about this. Thank you for great analysis :)

Apparently have to dig into qemu's code to understand this better, but first thought was that do you think it would be possible to add some crude hack bit in qemu's signal handler which we could 'almost atomically' check prior to entering system poll/select/read/whatnot ? This bit would tell there are user signals queued and handlers should be executed first.. ?
