Switching default segment=fast memory from hmm to lea
Switching default segment=fast memory from hmm to lea

The general impression is that lea may be the more stable
memory allocator, so I am switching the default to it in
order to get a regression run in this weekend and see how 
it compares.  hmm had a number of regressions due to not 
supporting a realloc call yet.
