[Bioperl-l] Bio::SearchIO blastxml for multiple queries

This has been fixed in CVS.  You will need to update to 1.5.2 since  
you're running bioperl 1.4, but I would recommend just installing  
from CVS if that's possible.

I will probably do some tweaking to the blastxml parser to better  
deal with multiple reports.  At the moment it parses the full XML  
output and caches the Result objects, so if you have a huge XML file  
it will likely choke your system.
