the program, Don Knuth's TeX adapted to GPC version 2.1, does heavy
I/O on text files. I noticed a very high percentage of system time.
I believe this is due to lazy I/O, which seems to be unbuffered.
GPC should apply lazy/IO when the text file comes from the keyboard,
but to use buffered I/O when it comes from the disk.
Is there a way to turn off lazy/IO on nonterminal text files?
