The backtrace after the crash showed one stack frame
calling __kernel_vsyscall.
Does anyone know what that does?

It's the syscall trampoline provided by the kernel.

It's the syscall trampoline provided by the kernel.
Could you explain more precisely?
Until very recently, I never saw Emacs stopped in __kernel_vsyscall.
Is it something fairly new?
Is there a way to determine which system call it is
by looking at some of the registers?

It's also known as vDSO. That's pretty much all I know about it.

It also contains the signal trampoline, so you may just be looking at a
signal frame.

signal frame.
If someone can tell me how to diagnose this, I would appreciate it.
I have started editing using the souces as of 2006-07-10.
We will see if it crashes. I have a suspicion that the sit-for
change is somehow responsible, but that is not yet proved.
