The issue is that Guile's ports are not threadsafe. I hadn't thought about this one... I am adding guile-devel to the Cc for input. Any fix to this will be pretty big, I think. I think that the right fix here is probably what Glibc does; see `info libc "Streams and Threads"` for the full details. Basically they add a lock to each FILE*, which is probably what we should do with our ports. We could investigate Java's biased locking, if that's useful. Andy -- http://wingolog.org/
