Well, it wasn't too hard to find a possible solution in the US patent
database.

Hello,
there are no asynchronous I/O primitives in IDL nor threading primitives,
so the only way I can think of is using a separate process to do the
reading and passing the data to the first process by shared memory. The
"reader" program doesn't need to be written in IDL.
But before you go that way, find out if your operative system's I/O
scheduler can be tuned for read-ahead.

Probably not. :-)
