[Isolate-interest] isolates and native libraries / shared memory

[Bernhard Fastenrath]

If I want to create a native library for unix implementing JavaSpaces 
between VMs or Isolates,
what assumptions can I make about Isolates?

If one isolate loads a native library, will another isolate be able to 
access the library?
If I try to shared memory identifier between Isolates, is there a 
situation where this
might fail? (for example Isolates running on different cluster nodes or 
similar concepts).
