I'm not sure this is a correct reason for mutexes instead of critical
sections. Either way, you need to have a strict ordering so that you
don't deadlock and critical sections use mutexes underneath. Unless
you're going to be using a named mutex to synchronise across processes
or you're going to have threads quit whilst holding the mutex, then the
only difference will be that the code is slower when using mutexes
because of the necessary server call, which more often than not can be
avoided with critical sections.
