Hi, Dan,

Now that Solaris is open source, it is conceivable that door library
will be ported to another platform, much like ZFS.

I have C code to implement most of the changes that I mentioned
above--I am using C, because I want to actually use the library to
make IPC calls.  But then, I'll have to copy the code in file.c mostly
verbatim, and make sure that the code stays current with the main
trunk.
