About 80 seconds on an x86_64

Performance depends on a lot of factors (platform, machine, etc).  By
default, remote-unwinding doesn't enable the cache, so it's certainly
relatively slow.  I don't think I ever ran into troubles with the 30
sec limit on ia64, but there isn't anything magic about that value
either.  How big did you have to make the timeout to make it pass?
What platform?  x86-64?

What is the performance of this test, I've found that with the
libunwind-20070224 snapshot I had to modify the alarm timeout to make it
pass. Is there a problem with the caching of the maps?
