 That semaphore will be reused everytime you run mono with the same
 user and same .wapi directory.

+Hi Gonzalo, thanks for the help on IRC.  I did some diging through how
+we build Mono in the FreeBSD ports system and I we set MONO_SHARED_DIR
+to the ports's work/ directory.
+
+[root at compass:ttyp1 mono-svn]# ls -al work/
+drwxr-xr-x   2 root  wheel   512 Aug 30 22:40 .wapi
+drwxr-xr-x  15 root  wheel  1536 Aug 30 22:36 mono-1.1.8.20050826
+
+I ran the semdel-wrapper manually after building Mono but the one
+remaing semaphore was not removed.  We need this semaphore to be
+removed because we remove the work/.wapi/ at the end of the build
+during the cleanup process.  We cannot write to ~/.wapi because we can
+only assume work/ is writeable during package building.
+
+I see that two .wapi/ directories are created during the build,
+work/.wapi/ and work/mono-1.1.8.20050826/runtime/.wapi/
+
+[root at compass:ttyp1 mono-svn]# ls -al work/.wapi/
+total 116
+drwxr-xr-x  2 root  wheel      512 Aug 30 22:40 .
+drwxr-xr-x  4 root  wheel      512 Aug 30 22:53 ..

+drwxr-xr-x  4 root  wheel      512 Aug 30 22:41 ..

+
+The shared_*-6-0 files under work/.wapi/ have file creation times
+which match the CTIME of the leftover semaphore.  I set
+MONO_SHARED_DIR=work/mono-1.1.8.20050826/runtime/.wapi hoping this
+would clear up the problem but instead the four files in the two
+directories listed above are all created under
+work/mono-1.1.8.20050826/runtime/.wapi/  I'm guessing the shared_*-6-0
+files are the problem.  Is there a way to prevent them from being
+created?  Thanks.
