 hrm, the version number of the wapi file was already bumped from the
 time this was made. But, the question is: how did the wapi file get
 into this strage state

+   We ran into something simliar today, and we tracked this down.
+The problem was that that we have a global SysV semaphore created in a
+per-user basis on the system.  The way we find about this semaphore is
+through the .wapi file.  If the .wapi directory is deleted (which
+happens with clean builds for example) without shutting this semaphore
+down you will encounter this problem.
+We had the exact same symptoms.  The new version of Mono will display
+the error message instead of sitting there waiting.  
+The problem was due to the way we build our Mono, so Dick wrote a
+small program that will cleanly shut this down, but we have not
+integrated this into the build yet.
+try as root to run `ipcs', you should see a number of semaphores with
+nsems=8 permission=600, those are most likely monos.  You must remove
+all the ones you are not using.
