[Bug general/4107] TestRunner is leaking file descriptors

["rmoseley at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

The limit on my FC5/i686 box for the file descriptors for TestRunner is about
1042 and then it aborts.  When I run the command Mike shows I see a couple of
processes running: TestRunner and funit-rt-asmstepper.  Running the "lsof"
command while running those, funit-rt-asmstepper appears to never open any
files.  If I run the "lsof" command on TestRunner I see the file descriptors run
up pretty quickly until the test aborts when it reaches ~1042 fd's.

Now, the weird thing is, when the test aborts, TestRunner remains in the cpu
queue but it now has a *totally* PID.  Doing a "lsof" on that shows about 1042
fd's open.  Looking at /proc/TESTRUNNERPID/fd and doing a list I see lines and
lines of this:

It seems nearly all the fd's are pointing to the funit-rt-asmstepper executable.
 Why would the TestRunner be repeatedly opening a fd pointing to the executable?
