It could easily occur just by virtue of the perl process picking
up the input data and exiting (killing its side of the pipe) before
gzcat has a chance to finish writing the manual page to the pipe.
It can also occur if the pipe buffer is small (causing gzcat to block
and then have the pipe ripped out from under it).
I'm thinking the best solution is to have makewhatis drain all remaining
input prior to closing the file handle.
