[racket] Pulling BLOB from SQL DB

While reading a BLOB from MySQL, DrRacket (5.2.1 on Win7) crashes
every time. (SQL was like 'select blobcol from table LIMIT 1')

Ran the same code via command line on Ubuntu. Racket seems to run out
of memory due to the size of BLOB.

Questions:

How can I give more memory to /usr/local/bin/racket?

Or more importantly,
Is there a way to pipe PORTs (in from MySQL and out to file) such that
Racket can handle 'very large' BLOBs?
