No, I was saying it's probably safe to read forever whenever the input
is a pipe. Sorry I wasn't clear. But if gunzip,etc. don't print error
messages I guess it doesn't matter.

BTW, is there a reason a pipe needs to be used for this? It seems like
it would also be possible to use the decompression code in the same BB
process rather than forking.
