Add some temporary code to record stack usage at server process exit.
This patch is meant to gather information from the buildfarm members, andwill be reverted in a day or so. The idea is to try to find out thehigh-water stack consumption while running the regression tests,particularly on IA64 which is suspected to use much more stack than otherarchitectures. On machines with pmap, we can use that; but the IA64 farmmembers are running HPUX, so also include some bespoke code for HPUX.(I've tested the latter on HPUX 10/HPPA; not entirely sure it will workon HPUX 11/IA64, but we'll soon find out.)Discussion: <CAM-w4HMwwcwaVvYcAH0_FGtG5GeXdYVRfvG81pXnSJWHnCfosQ@mail.gmail.com>
