Some of them are fixed if you build ORBit with --enable-purify-friendly
(or something like that, look at configure --help to see what the option
is called).

Essentially ORBit doesn't bother to initialize the padding in the IIOP
protocol, so when it calls write() some of the bytes written are
uninitialized.

There may be other problem reports too, you'd have to investigate each
one.
