We're primarily interested in having a library for our own use, so
prime emphasis is on clearly separating OS dependent from OS
independent parts. How to keep as much as possible of the OS-dependent
bits portable is an issue we'll look at when we are facing the
problem.
Good news was that the port of the first part from Unix to Mungi
involved mostly debugging Mungi rather than the library ;-)
