I think this interface is fine as a low-level interface. However, I
think it should be dressed up as functions in the omniORB module,
which take TypeCodes as the arguments, rather than the type
descriptors.

Something like

  encap = omniORB.cdrMarshal(foo, MyIDLModule._tc_MyIDLStructClass)
  foo2  = omniORB.cdrUnarshal(encap, MyIDLModule._tc_MyIDLStructClass)

I'm not sure what the problem is there. Some time soon, I'm going to
do a pre-2 release of omniORBpy, which involves some fairly
significant rearrangement of things. I'll add the CDR (un)marshaling
functions as part of the release. When I do that, I'll think about the
memory management.

Cheers,

Duncan.

PS. I've finally got around to integrating your patches for building
on x86 NextStep. Thanks for that.
