This silly restriction is only because dlopen()'ing the same file
twice doesn't map in the library twice, instead you just get another
reference to the already-mapped memory. This is really a deficiency
in the dlopen() API IMHO that the JVM inherits and consequently is
limited by.

If you could dlopen(..., RTLD_COPY) or whatever then this problem could
go away... also, a gross hack would involve copying the library to /tmp,
dlopen()'ing it, then removing it.
