Subject Re: [general][signal] I encountered some signals when debugging VM
Date Mon, 29 Oct 2007 12:44:51 GMT
Hello Simon,

I have the following line in my .gdbinit
handle SIGUSR2 nostop noprint

I put this line when signals were used to flush a cash, and your
experience shows that they are still used.

Thanks.
