[Bug testsuite/4696] New: profile.exp fails with "probe overhead exceeded threshold" error message


My environment is Systemtap-20070623 snapshot,elfutils-0.125 and kernel-2.6.22-rc5.

When I executed this week tests, I got this error message on execution of
profile.exp. Error message tells that system has spent more than
STP_OVERLOAD_THRESHOLD cycles of time on this probe.
=================================
Running
/home/systemtap/tmp/stap_testing_200706250605/src/testsuite/systemtap.samples/profile.exp
...
ERROR: probe overhead exceeded threshold^M
WARNING: Number of errors: 1, skipped probes: 0^M
FAIL: profile
testcase
/home/systemtap/tmp/stap_testing_200706250605/src/testsuite/systemtap.samples/profile.exp
completed in 15 seconds
===============================

I tried to reexucute the same test individually but problem didn't get
reproduced. Is some race involved with this??
