[BioC] memory exhausted for readAligned

[Lana Schaffer]

Patrick,
Do I need a 64-bit windows computer?
Where is the code for the R v2.9.0dev Unix version?

Lana,
Given that there is typically a trade-off between memory and speed and
the ubiquity of 64-bit machines, most of the Bioconductor sequencing
software was designed with 64-bit architectures in mind in order to
minimize computation time. Once you move to a 64-bit machine for this
work, I'm pretty sure this issue will go away.
