Hi! I just wanted to tell you that I have fixed some nasty MT-safety issues with handful of library calls in Tcl. The affected ones were: getgrnam, getgrgid, getpwnam, getpwuid, gethostbyname and gethostbyaddr.
Now there are wrappers there which fallback to the MT-safe version (if available) or, if not, perform the operation under mutex protection. The latter not being an ideal solutiuon as some other lib may also call the problematic function w/o lock (or under different lock) but this is better than nothing. If you use lots of [file attributes] or [socket] or [fconfigure $sock] chances are that you are going to be hit by the bug. In that case update to CVS version of the Tcl lib (core-8-4-branch). Cheers Zoran
