showstack: also handle SIGALRM
This is looking *very* handy when debugging mysterious hangs in a
test: you can wrap a hanging invocation in
`perl -e 'alarm shift @ARGV; exec @ARGV' 1`
for example, a hanging `hg pull` becomes
`perl -e 'alarm shift @ARGV; exec @ARGV' 1 hg pull`
where the `1` is the timeout in seconds before the process will be hit
with SIGALRM. After making that edit to the test file, you can then
use --extra-config-opt on run-tests.py to globaly enable showstack
during the test run, so you'll get full stack traces as you force your
hg to exit.
I wonder (but only a little, not enough to take action just yet) if we
should wire up some scaffolding in run-tests itself to automatically
wrap all commands in alarm(3) somehow to avoid hangs in the future?

==================================== Testing head checking code: Case C-3 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category C: case were the branch is only partially obsoleted TestCase 3: 2 changeset branch, only the head is pruned .. old-state: .. .. * 2 changeset branch .. .. new-state: .. .. * old head is pruned .. * 1 new unrelated branch .. .. expected-result: .. .. * push denied .. .. graph-summary: .. ..
