parfor with BioIndexedFile?

Is it possible to use parfor with a BioIndexedFile? I have tried, and Matlab seems to gag on it.

Example:

B=BioIndexedFile('fastq','P.fastq');

parfor n=1:1e6

a=read(B,n);

%some operations here
end

It doesn't seem to matter how simple the operations are. The machine runs out of memory, and doesn't seem to start the task. Perhaps it is trying to make a copy of the BioIndexedFile for each worker?
