I've created a pull request with a description of the problem, and a
suggested fix:

https://github.com/jsoftware/jsource/pull/6

I gather that the github repository isn't really used for pull
requests based on past threads on the mailing list but thought this
would be a useful way to post the problem and what I think is the fix
and you and others to see if it is indeed the problem.

It doesn't fix the 1!:1 issue of using seek to get the file size of
the stream, where pipes are non-seekable, but does fix 2!:2 and stops
1!:20 from crashing after a 2!:2 call. There was a discussion on irc
today about what the 1!:1 and other issues are with possible
approaches to try.
