Summary: Potential crash when starting concurrently

Initial Comment:
When concurrently starting a REXX script from java, BSF4ooRexx seems prone to crashing (taking the JVM down with it).

See the attached test program to reproduce and a crash report. It doesn't consistently crash 100% of the time, but usually it does. Raising the THREADS constant seems to increase the likelyhood of the crash.
The vulnerability seems to be mainly while starting the REXX script: If it does start successfully, it seems to keep running as it should.

Message:
I've tested it with the 20130107 beta version, and unfortunately I could
still crash the JVM with the TestConcurrencyCrash.java test program
(although perhaps it happens less frequently).

This is in the JVM crash log:
#
# A fatal error has been detected by the Java Runtime Environment:
