+Summary: mcs goes into infinite loop when no sysv semaphore is available
+
+Description of Problem:
+When no sysv semaphores are available, mcs goes into an infinite loop.  It
+should exit with error.
+
+Steps to reproduce the problem:
+1. Use some method to tie up all sysv semaphores on a system
+2. start mcs
+
+Actual Results:
+mcs goes into an infinite loop (ran for over 14 hours before I discovered
+the problem) eating up 100% CPU and constantly outputting the error "**
+(/usr/local/lib/mono/1.0/mcs.exe:56776): CRITICAL **:
+_wapi_shm_semaphores_init: semget error: No space left on device.  Try
+deleting some semaphores with ipcs and ipcrm"
+
+Expected Results:
+The error is OK, but mcs should exit nonzero instead of looping indefinitely.
+
+How often does this happen? 
+Every time I've tried it.
+
+Additional Information:
+mono-1.1.13.8.1 installed from FreeBSD ports.
