That's a useful enhancement request, for making sure LC degrades 
gracefully in low-memory situations.

But that seems different from what Roland was asking about.  He needs to 
work with a 38GB file, beyond the memory address space of LC, and 
impractical for many programs.

When faced with a file that large most apps will read it in chunks, and 
as of several versions ago LC can do this gracefully:  "seek" and "read 
at" were enhanced to allow locations as large as the host file system 
permits.  With this we can traverse files far bigger than would be 
practical in RAM.

Oddly enough, when I was experimenting with chunked reading I started 
with 10 MB chunks, thinking the less I touched the disk the better.  But 
I found my routines got faster as I tried smaller reads, all the way 
down to about 130k where the comparison leveled off.  Apparently memcopy 
is not with its own overhead.
