maximum recursion depth?

[globalrev]

i  received an error maximum recursion depth when processing large
amounts of data.

i dont know exactly how many recursive calls i made but id assume
50000 or so.

is there a definitie limit to the nbr of calls or is the memory that
runs out? is that then the RAMmemory? is there a special amount of
memory assigned for python or it just takes and takes until windows
runs out of it?
