yeah, i remember i was also missing that when debugging.. i found stuff about signals myself, but not the other parts.
Thanks.

I want to debug asm instruction per instruction with gdb, but the heartbeat keeps interrupting. Is there a way to disable it or make gdb ignore it in some way?
Yes, at two levels. First, signals, via
handle SIGUSR1 nostop noprint noignore handle SIGUSR2 nostop noprint noignore handle SIGALRM nostop noprint noignore handle SIGPOLL nostop noprint noignore handle SIGPIPE nostop noprint noignore
etc. This can and should be put in ~/.gdbinit (find mine attached; note its called gdbinit only because I can't attach .gdbinit; you need to rename it when you install it; pbreg prints my Bochs instance in the JIT simulator; feel free to delete that :) )
Second, to avoid the effect that the heartbeat has on control flow (e.g. causing a process switch) you can set suppressHeartbeatFlag to 1 via
(gdb) set var suppressHeartbeatFlag = 1
