To summarise to refresh memories there was a patch proposed using SIGINT followed by discussion as to why SIGINT wasnt ideal because it would cause regressions for anyone relying on the existing handling of SIGINT, and various other signals were considered including HUP & USR1 & USR2 all of which are already used for something else.
Is SIGPWR a suitable candidate, I have made a patch to use SIGPWR but as Im new to QEMUs internals Im not sure if there are any circumstances in which an alternative handler is registered for SIGPWR which might conflict?
Regards Andrew
