I'm a bit concerned about mod_rewrite safety on servers with many users.
I see there is a MaxRedirects option which defaults to 10, but afaik users may
override this. Also, there is the [N] flag to RewriteRule which
documentation says:

<CITE> Use this flag to restart the rewriting process, i.e., to immediately
go to the top of the loop.
<B>But be careful not to create an infinite loop!</B>
</CITE>

I would like to ask, does the MaxRedirects apply in case of using this flag?

No. Be aware of PR 38642 (http://issues.apache.org/bugzilla/show_bug.cgi?id=38642), the problem described there can cause a situation which leads to infinite looping.
