Good idea, but I doubt that Numeric ever uses realloc(). A search
through the code and/or a post to the NumPy list will tell you.

From your brief description, you wouldn't take a performance hit.
numarray is slower when creating new arrays, but if you're working with
big arrays, then the creation time is small anyway, compared to doing
things with them. Numarray can be faster than Numeric for some
operations with large arrays.
I don't' think it's likely that numarray will solve your problem, but if
it does, it will give you hint as to what the problem is.
