Watch out for get_bytes().

If you say

    sequence blk
    integer handle
    handle = open( "HUGEFILE.DAT", "rb" )
    blk = get_bytes( handle, 72000000 )

then be prepared for a bit of a wait. Yes, there's the wait while the data
actually gets sucked off the disk, but there's also the wait while get_bytes
executes a repeat() to set aside the memory, and then the loop from 1 to
72000000 while get_bytes() gets each byte (individually?!). Added to all that is
the memory and disk swapping that goes on while the underlying system tries to
provide the memory. Add it all up and you've got a big performance hit.

Question to the Euphoric Community: is there anything better out there than
get_bytes(). Any Windows function?
