[Xen-devel] [PATCH] ioemu-remote: check shutdown_requested timely.

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

After a recent merge of the ioemu-remote tree several weeks ago, I find in 
main() -> termsig_seup(), ioemu sets a SIGHUP handler that sets a global 
variable shutdown_requested to 1, but ioemu doesn't check the variable and as a 
result, ioemu wouldn't terminate when xend sends a SIGHUP to it; finally xend 
has to send a SIGKILL to it in 10 seconds. The small patch adds a check to 
terminate ioemu timely.     

Thanks,
-- Dexuan
