The OS dependencies of the core harmony VM should be very minimal. In the case of Jikes RVM, there is a very thin layer of C code that interfaces to the OS (signals, system calls, bootstrap). OS ports are fairly straightforward and very well contained within this interface. Therefore I don't see OS portability as a concern for the core Harmony VM. Portability of the libraries is a bigger issue.
do you think APR would help there?
