Similarly to bug #2185, because we don't have a separate stack for kprobe
handling (bug #931), we may have stack exhaustion problems in ordinary usage
without reentrancy.  We go out of our way to minimize stack usage, but we need to
- estimate or measure stack usage of a worst-case scenario (kprobes handler,
deeply nested systemtap expression, calling into the most complex runtime routine)
- add code to the probe entry functions to check for available stack space, and
punt (skip probe) if it's not sufficient
