Thanks for warning me that it's somewhat mutex-happy.
Perhaps that can be fixed, but that'd be one more thing I'd have to do.

And my motivation for controlling memory-allocation wasn't speed, it was to make sure I don't exceed my budget, or cause stability problems (e.g. memory fragmentation), in an embedded environment.
