Comment (by yawning):

 > Apparently a third option would be to teach Firefox to hook the sigsys
 signal, and then it could log something about what it was doing at the
 time it got the signal. That involves some programming -- and I wonder if
 the timing is fine-grained enough that Firefox at the time of the sigsys
 signal can identify exactly which syscall it is doing?

 This is fine.  The `siginfo_t` that the signal handler will get contains
 all the relevant information.
