commit 5ed19be2fdeac594f8e3ba4fc7aa75c598303ad8
Author: Dave Brolley <brolley@redhat.com>

Handle resource limit violations of stap when called by stap-serverd more elegantly.
- Catch SIGXFSZ and SIGXCPU in stap and in stap-serverd.
- Exit gracefully from stap when caught.
- In stap-serverd, compare the current limits against the original limits
and continue if the current limits are less (i.e. are limits intended for stap).
- Set/restore limits around stap_spawn instead of spawn_and_wait.
