I use this extensively in my own framework, simply because there's no
other way for me to perform particular tasks (filtering and output
caching for example). But even when creating long and complex pages with
a lot of nested objects, each storing its own output buffer, this has
never become a memory issue for me. My most complex page until now (with
55 database queries, 111 loaded classes, 324 objects created while
script execution, 344KB final HTML code) just consumes 8.1MB.

I'm pretty sure that this is the reason, but without knowing some code
it's impossible to say. It might help to call memory_get_usage() from
time to time to see where the real hole is.
