Summary: Crash in TExecuter_HTP with VUs >= 1666

Initial Comment:
I'm seeing an easily reproducible crash with OpenSTA
1.4.3.20 on Windows XP Pro SP2.

1. In the Commander, create a test and add a task group
with any test script.  I reproduced the crash using a
variety of scripts, including a skeleton script no with
executable statements at all.
2. Click the cell in the Start column and choose a
method for stopping the task group.  The crash is
reproducible with any of the options - Manually, After
fixed time, and On Completion.
3. Set the number of virtual users for the task group
to 1666 or more.
4. Run the test.  When it completes, I get the error
"TExecuter_HTP.exe has encountered a problem and needs
to close."  Sometimes the error repeats when I dismiss
the error dialog, for a total of 6 times.  

The Commander seems to still be running fine, though
I'm not sure if the results are recorded correctly. The
Test Error Log shows an error for the location
"TestExecuter" - "General exception while running the
thread pool." This error also appears when I run with
1665 virtual users, though I don't reproduce the crash
in that case.

The workaround seems to be to not try to use more
virtual users than OpenSTA can handle (as per bug #696350).
