Which is fine for this app, so I will.

Yep. I screwed up the import statements - I'll re-do it tomorrow. In that light, it is interesting that the assign N were always longer than the n ones...

Will do. I am also a little concerned about the address changing in a long-running process (literally, weeks), so I might check that too.
Also, why is assignment from a (ctypes.c_long * 2000)() to a numarray so much slower than a memmove()? Does the assign make a temp buffer?
