Cool.

William and I spend an evening on the current OSX 64 bit problem - see
#5862. We fixed one issue that is caused by different dlopen behavior
by explicitly using dlsym() to get siInit() since it wasn't executed
at all on 64 bit OSX.

But fixing that issue still does not fix the segfault at startup. What
is happening is oMalloc not being properly initialized and going boom
the first time a ring is instantiated. I tried compiling oMalloc's
check target on OSX in 64 bit mode, but failed after only spending 5
minutes on the problem. Turning on debugging did not help for any of
the oMalloc issues. It seems that the initialization for oMalloc
mysteriously works for some releases while it is completely broken for
other releases, so we need an oMalloc expert to fix this :). Reverting
the fix GSW did for the mmap vs. sbrk problem did not revert the
problem either, so I am fresh out of ideas :(
