[Bioperl-l] Blast temporary open files not closed

Processing a fasta file with about 500 dna seqs.. my MacOSX (that
has the max number of opened files up to 512) crashes... You need to
divide the problem in pieces or (in bash shell, with ulimit -n 1024)
augment that max number of opened files.
This has no sense for me since my perl program nor leave any open
file without its corresponding closing. On the other side, the
problem arises when the number of dnas grows _in one file_.
In the code I run blast (StandAloneBlast... $blastMachine->blastall)
for each seq.
Then sniffing int the perl program stopped perl program I confirmed
my suspects. BioPerl (StandAloneBlast) does not closes temporary
opened files. Those files seems to be created to save seqs for to be
then processed by blastall program... The output of lsof indicates
(as MacOSX System Monitor) that those files are left opened but not
there (!?)
The output of lsof +p pidofperlprogram
