Thanks. If you come up with anything, please file that bug report. I 
certainly regard this as an important thing that must be fixed, though I 
don't know if I should hold up release of 1.5.2 for it. Now that you've 
reported on it I'm leaning toward yes, since the new Bio::Species 
implementation is one of the major new features of 1.5.2 and it ought to 
work well.

Anyway, for the memory leak I have some ideas I haven't tried yet; I 
don't know if my efforts will solve the speed issue though.

If anyone can spare the time to look at the problem, please do.
