Fran broken with Feb 2001 Hugs

Hi Sean. Some bad news. The Feb'01 Hugs release has a representation change for IO, breaking Fran's Compatibility.safeTry, which I had copied from Alastair Reid's graphics library. I noticed that the graphics library is broken for the same reason. I worked around that problem, but then I get "Program error: no more threads (deadlock?)" on even the most trivial Fran example. That kind of error is usually very hard to track down. Hugs-bugsers: any guesses about the thread deadlock problem? Also, as a possible temp solution for Sean, is the previous version of Hugs still available somewhere? Thanks, - Conal
