Hi Michael,

I am the author of the changes to UNIXProcess_md.c.
File descriptor 3 is used to communicate any cause of failure
back to the parent process.

One might think that the openjdk7 code would work on
BSD because if the standard way of opening /proc/self/fd,
it falls back to closing all descriptors up to sysconf(_SC_OPEN_MAX),
which one would think the BSDs would have implemented.

In any case, even if the current jdk7 code doesn't work on BSD,
it should be easy to create a small patch to it that would be
portable to more Unix systems, that could be accepted upstream.
I would be willing to review.
