Getting a better containers unit is nice, but the root of the problem 
seems to be the memory manager.  Delphi's old memory manager had 
fragmentation issues also.  That is why NexusMM, BucketMM and FastMM we 
created.  FastMM is now included with Delphi as the main memory manager. 
  Not only does it solve memory fragmentation issues, it is much faster 
than the old memory manager (especially in multithreaded apps).

FastMM is open source, has anyone ported it to FPC?

I seem to recall that when it began to be used in Delphi, it uncovered 
lots of memory bugs in the IDE and runtime.  When these were fixed, 
Delphi became a much more stable product.
