The system I'm having the most leak problems on is already using 8.4.6,
unfortunately.  But I'd like to try your test code anyway and see what
happens.  Where do I get this Threads extension?

OK, looks like Tcl 8.4.7 introduced the leak. Here's my test run against Tcl 8.4.6:

    $ LD_LIBRARY_PATH=`pwd` ./tclsh
    % info patchlevel
    8.4.6
    % lappend auto_path /usr/lib/tcl8.4; package require Thread
    2.6.1
    % exec ps -p [pid] -o pid,vsz,rss,args
      PID   VSZ  RSS COMMAND
     8317 12704 1996 ./tclsh
    % for {set i 0} {$i < 1000} {incr i} {
        thread::join [thread::create -joinable {}]
    }
    % exec ps -p [pid] -o pid,vsz,rss,args
      PID   VSZ  RSS COMMAND
     8317 21192 2272 ./tclsh

Same test against Tcl 8.4.7:

    $ LD_LIBRARY_PATH=`pwd` ./tclsh
    % info patchlevel
    8.4.7
    % lappend auto_path /usr/lib/tcl8.4; package require Thread
    2.6.1
    % exec ps -p [pid] -o pid,vsz,rss,args
      PID   VSZ  RSS COMMAND
     9358 12692 2000 ./tclsh
    % for {set i 0} {$i < 1000} {incr i} {
        thread::join [thread::create -joinable {}]
    }
    % exec ps -p [pid] -o pid,vsz,rss,args
      PID   VSZ  RSS COMMAND
     9358 48272 29432 ./tclsh


If anyone wants to review the changes to Tcl between 8.4.6 and 8.4.7, you can produce the diff like this:

    $ cvs -z6 -d :pserver:[EMAIL PROTECTED]:/cvsroot/tcl rdiff
-rcore-8-4-6 -rcore-8-4-7 tcl > tcl-846-847.diff

In the meantime, everyone who is seeing unexplained nsd memory growth
if
you're running Tcl >= 8.4.7, please roll back to Tcl 8.4.6 and see if
that makes the problem go away.  (Andrew?  Janine?  etc.)
