New Revision: 34500

Modified:
   labs/jbosstm/workspace/emma/emma-2.0.5312-trunk/core/java12/com/vladium/emma/rt/RTExitHook.java
Log:
patched RTExitHook so it checks for System property emma.exit.delay and if it is set and can be parsed to an integer value waits the specified number of seconds before dumping coverage data. this allows coverage data to be collected for other at-exit code
