Rob Thanks for the background info. I wasn't very specific in my last question. Actually I meant to ask why doesn't qemu code set sigaction(SA_RESTART) for _all_ signals when running in system emulation mode (or maybe it does, which means there's even larger problem...) --Yigael

Fallout from old 1980's-era Unixes that didn't implement SA_RESTART, basically. Standards like SUSv3 say to humor them, because they paid for the standard... http://www.ussg.iu.edu/hypermail/linux/kernel/0507.1/1065.html > --Yigael Rob -- "One of my most productive days was throwing away 1000 lines of code." - Ken Thompson.
