 you'll see that things start to go slightly better.
 Often I get MemberAccessExceptions from GDI+, which means
 that a GDI+ object that was created in one thread is
 consumed in another thread. I bet there are some static
 shared objects inside SWF.

+BTW, mono_marshal_get_native_wrapper() uses
+mono_marshal_find_in_cache() which in turn takes the marshal
+lock and lookups the cached wrapper. If is was not in
+cache, it releases the lock and starts generating the
+wrapper.
+
+Of course, 2 threads might be generating the same wrapper at
+the same time, but this doesn't hurt. It's far better than
+having a big lock around mono_marshal_get_native_wrapper().
