Differences From Artifact [9ee435cd1e]:

• File misc.h — part of check-in [e84a3c910c] at 2001-08-25 12:09:23 on branch trunk — Extensive changes that _should_ fix the socket buffering problems, by ceasing to listen on input channels if the corresponding output channel isn't accepting data. Has had basic check-I-didn't-actually- break-anything-too-badly testing, but hasn't been genuinely tested in stress conditions (because concocting stress conditions is non- trivial).

To Artifact [008301a75c]:

• File misc.h — part of check-in [0963d65406] at 2001-08-26 10:31:29 on branch trunk — Further tightening up in PSCP. Fixed a couple more holes whereby a malicious SCP server could have written to areas other than the ones the user requested; cleared up buffer overruns everywhere. Hopefully we now do not use arbitrary buffer limits _anywhere_. (user: simon size: 1322)
