Ah... That's clever. I'll give that a try.

According to the POSIX standard write() is one of the calls that you can make from a signal handler.

Thanx,

Jason,

I had exactly the same issue as you and was told not to use
any Cocoa calls in a signal handler. My solution was to create
an NSPipe, do a readInBackgroundAndNotify on the read end,
and then from the signal handler just do a write(2) directly
on the write-end file descriptor.

This works well, and I later saw on the Darwin developers
mailing list somebody recommending this writing-to-a-pipe
from a signal handler trick, so I guess it is pretty safe.

I.
