The LD_PRELOAD is working out after all. I set this *inside* of my '.java_wrapper'
instead of on the command line. This prevents the process from hanging like before.
LD_DEBUG=symbols,binding.... reveals the following:
31566: symbol=putpmsg; lookup in file=/usr/lib/libLiS.so
31566: binding file /home/imslab/jets1000dev/dlpi/libdlpi.so to /usr/lib/libLiS.so: symbol `putpmsg'
Thanks for the help!

This not Java specific, you'll get the same problem when dlopening a
library which is linked against libLiS.so. The first getmsg which
gets found is from libc.
If you set LD_DEBUG=symbols,bindings you can see what's happening.
(E.g. "LD_DEBUG=symbols,bindings java ... 2>&1 | grep getmsg")
In order to get getmsg() from libLiS.so you either have to set
LD_PRELOAD=libLiS.so or create a new startup program (which you'll use
instead of "java") that is linked with libLiS.so.

No, the restriction only applies to the green threads VM.
