+Summary: Multithreaded program sometimes exits unexpectedly on Mac OS X
+
+Description of Problem:
+A simple multithreaded programs using the ThreadPool sometimes exits or 
+hangs unexpectedly on Mac OS X, even with a small number of threads.
+
+Steps to reproduce the problem:
+1. Run attached sample program, giving a small number of threads such as 2 
+or 4
+
+Actual Results:
+On some runs, the program exits without printing any lines, or exits very 
+quickly, within a second or two.
+
+Expected Results:
+The program should continue to dump output lines until I ctrl+c it.
+
+How often does this happen? 
+As much as about half the time (13 of 20 runs I just tested).
+
+Additional Information:
+Mono 1.1.7 installed from the .dmg package http://www.go-mono.com/archive/
+1.1.7/macosx/MonoFramework-1.1.7.dmg
+Mac OS X 10.4.1 upgraded from a 10.3 installation; Mono was installed after  
+the upgrade. (Earlier versions of the Mono framework were previously 
+installed and deleted before this version was installed.)
+Machine is a single-processor G4 PowerBook.
