a) I'm confused: I know that those ports are in the thread state, but I'm confused about interaction of call/cc and threads: are dynamic-wind's all executed upon each thread switch or not at all? This is especially interesting wrt. to parameters too. b) I noticed meanwhile that this "fix" did at least not fix the problem I have: output from elsewhere appearing in the file I opened by with-output-to-file - probably because the output came from ##sys#schedule/switch c) my patch uses in with-*-*-file the same code structure as for instance unit ports with-*-*-string. Why should one do it this way and one the other way? > Additionally, it may not always be intended to close the port > when an escaping continuation is used, as the current state > could be re-entered. I understand your remark, but I don't understand it's relationship to the code in question. IMHO the escaping continuation should not close the port. /Jörg _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
