Comment (by michael):

 DataStruct::WriteCache and nsIOutputStream::Write don't deallocate the
 memory in aData. If you look closely, nsMemory::Free(buff) only frees the
 'buff' memory that was deep copied from aData by
 nsPrimitiveHelpers::CreateDataFromPrimitive.

 Before proposing a preference, it might be wise to do a real world test to
 confirm this. If confirmed it makes no sense producing the cache disk
 files under any conditions (even the stock Firefox) whatsoever.
