[Bug runtime/2725] New: Attempting to probe all kernel functions hangs FC5

Attempting to probe all kernel.function's hangs FC5

I'm not sure how realistic a test this is - but it is 100% reproducible on my
Fedora Core 5 system.

Invoking stap with this command hangs the system - power cycle required to clear:

stap -v -p5 -e 'probe kernel.function("*")  { printf ("%s  %s  %d  %s  ",
"test-> ", execname(), pid(),  probefunc() ) }'

I'm not yet sure if one probe is causing the hang - or the accumulation of 10K+
probes. 

Systemtap version (built from CVS head 20060601):
  SystemTap translator/driver (version 0.5.7 built 2006-06-01)
  (Using Red Hat elfutils 0.120 libraries.)

Kernel installed:
  kernel-devel-2.6.16-1.2122_FC5
  kernel-debuginfo-2.6.16-1.2122_FC5 
  kernel-2.6.16-1.2122_FC5
