It's listed in the caveats section of the sample's documentation.
Due to a bug in the system software, this sample may be unreliable
when run on Mac OS 9.1. The problem is that MPRemoteCall sometimes
deadlocks the system on Mac OS 9.1. The only workaround is to not
use Mac OS 9.1. The problem does not occur on Mac OS 9.0.x and is
fixed on Mac OS 9.2.x.
The problem is that 9.1 can mess up the RPC associated with
MPRemoteCall, which causes the MP thread never to unblock. I might
have been able to work around this in OTMP itself, but other MP
services (such as MPAllocateAligned!) use MPRemoteCall, so there was
little point.
