I've tried the patch and it makes a good improvement in the number
of system calls made.  There is still a bit of re-reading of the same
block as (I assume) it leaps back and forward to the table of contents.

However, I note that stdio was explicitly taken out of jar.c:

	revision 1.2
	date: 1998/05/28 20:13:46;  author: cvs-gback;  state: Exp;  lines: +15 -10
	removed use of stdio in jar.c, added JARFILES debug target

So whatever the issue was that lead to it being removed needs to be
resolved -- if it still applies.
