There seems to be little to no documentation on these various internal
functions.  E.g. How are read, IO_Read, and JVM_Read supposed to differ?
 Where's the interface doc?

Many years ago I filed
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4904617
that remains unaddressed :-(
Perhaps as part of this change or set of changes, that bug could be dealt
with?
Perhaps even by deleting JVM_Read?
