My malloc manual says that it uses mutexes "internally to 
protect the memory-management data structures employed by 
these functions" (alloc, free, etc.) to avoid corruption.
Or do I miss something?

Audio codecs generally don't use multi-threading and 
should therefore not require special treatment.
