+Yes - I tried this (with a suitable #undef) here is what happened:
+
+TLS               VAR_OFFSET          Result
+initial-exec      <as normal>         crash
+initial-exec      -1                  crash
+local-dynamic     <as normal>         crash
+local-dynamic     -1                  * works * :-)
+
+And of course OO.o works fine with the last case here.

+
+So - the semantic difference between a shlib and a module is unclear
+to me. However - if we want people to add Mono scripting support to
+their applications, this will of course frequently be done using
+plugins - OO.o is just the tip of the iceberg: Mozilla, gedit ;-) ...
+
+Apps in general will not want to hard link directly to libmono if they
+can avoid it, that sort of hard build & run-time dependency is rather
+unpleasant surely [ not to mention degrading startup performance for
+when it's not actually used ].
+
+Wrt. renaming libmono - to libmono-module: if that works for you, I'm
+fine with it [ any solution is good I guess ;-]. OTOH - surely having
+a statically linked version to 'mono' will make 'mono' even smaller,
+more efficent & faster to start.
