	ah! Perhaps this is the source of the gzip problems I've been
having.  Your script fails for me:
NetBSD 1.5R (DIANA) #3: Wed Feb 14 23:13:01 CST 2001

However, you can simplify the test program: anything which seeks
beyond the end of the file will cause this behavior.  I am
quite reliably getting fragments of other files by writing
one byte and seeking 4k beyond it.
