Currently, the Sage signal handling code does not handle stack overflows gracefully. Fix this using sigaltstack().

In fact, change the whole design of the signal handling to use GNU Portable Threads which is quite natural once you see it. It immediately also gives a much better solution to #12873.

Apply attachment: 13076_sig_pth.patch

Install the new spkg http://boxen.math.washington.edu/home/jdemeyer/spkg/gnu_pth-2.0.7.p0.spkg

Depends on #12873

Not very well tested yet, but seems to work on Linux and OS X 10.6.

Never mind, this is totally not supported on OS X 10.4.
