This is definitely doable, but it would require a lot of work: the old
dll has to be unloaded (which needs code in probably importdl.c) and
also a different CodeWarrior runtime library should be used (the
DropIn one in stead of the SharedLib one, if I remember correctly).
I don't have any time to spend on this, but if anyone else wants to
implement this I'll incorporate it.
But, on a tangent, if my extension is so complicated it needs
debugging I usually debug it by incorporating it into
PythonStandSmall. The CodeWarrior debugger always seems to work better
for me if I use it on a statically linked program in stead of on a plugin.
