Yes.  This provided a significant performance improvement, however it has 
some serious drawbacks

  a.. I experienced some crashes during testing
  b.. Commercial licensing is expensive
  c.. It 'hooks' system calls to malloc, a technique I consider dodgy.
  d.. It is a DLL, which I avoid since they result in endless configuration 
management nightmares.

Gosh!  Did I suggest anything like this?  However, a well designed 
multithreaded program will slow down, rather than speed up, on a 
multi-processor machine when the standard memory allocator is used which 
took me, at least, completely by surprise and mystified me for several days.
