This alternative won't help you when:
* the pythonscript is sensitive to the context AND
* it is called w/ 2 or more different contexts on the same request
An artificial example I can come up w/ from the top of my head:
Suppose you have a folder w/ an index_html that displays information
about it's subfolders that is calculated by an expensive script and you
want to cache the results of this script, you'd go:
<ul>
<li tal:repeat="subfolder python: here.objectValues('Folder')">
Folder <span tal:content="subfolder/title_or_id"> contains
<span tal:content="subfolder/expensively_calculate_shruberries">
shruberries.
</li>
</ul>
Then you'd go and RAMCache "expensively_calculate_shruberries"
But if we implement the change you're suggesting, then this page would
list the same number of shruberries of the first subfolder for all of
them.

This annoyance is indeed related, but the proper fix is for
FSPythonScript to have a ZCacheable_manage page that takes into account
the fact that it's usually part of a portal_skins setup and deal with
it. Alternativelly, portal_skins should provide the functionality of
expiring RAMCached subitems.
