[wp-hackers] XCache Variable Storage vs. WP Object Cache

Technically XCache only has a variable cache ATM, so that might
explain that limitation >.<
Is it *safe* to serialize all objects coming in and unserialize them
again going out? I know in some other projects I worked on there were
stuff you weren't supposed to serialize or the sky would fall (or
something like that).
I've been searching, but can't find an answer to this:
In PHP, is there an easy way to check if something is an object? I
know PHP's lax (for lack of a better word) (or rather, nonexistent)
datatyping makes this kind of hard, but it would highly improve
performance if I only serialized items that weren't normal
