According to the comments sent by Bill, this fixed a problem where telnet was walking on top of another data structure I quote (with slight modification for politeness sake) To fix obscure telnet bug (it "messes up" another data structure in the process, because it's using a "freed" process e.g. free()): Unfortunately, for lack of time and lack of familiarity with the code, I didn't know what would be affected by the fix. As far as the original distribution, (this is what the patchkit is for), the only routine that still needs to be fixed is the com driver. (If X is hogging all the resources with the new patchkit, get Chris's new com driver, since it contains the fixed select stuff) Nate -- osynw@terra.oscs.montana.edu | A hacker w/out a home. work: (406) 994-5991 | Keeper of the Unofficial 386BSD Bug Report home: (406) 586-0579 | Please send bugs and/or fixes you find.
