[Zope] recursive iteration in External Method

[Tino Wildenhain]

Hi Elena,

it does not look like your recursion does not work
properly but perhaps you are activating too many
objects and so run out of memory and get into timeout.
May be you should try it with a much smaller subtree
and if it works try to use sub-transactions (like ZCatalog
does) to avoid intensive memory allocation.

Regards
Tino
