<tt>Sorry, I omitted that. My example gives the following error:</tt><br>
<br>
<tt>Error from thread tid00000C20</tt><br>
<tt>invalid command name "tclPkgUnknown"</tt><br>
<tt> while executing</tt><br>
<tt>"tclPkgUnknown XOTcl {}"</tt><br>
<tt> ("package unknown" script)</tt><br>
<tt> invoked from within</tt><br>
<tt>"package require XOTcl"</tt><br>
<tt>User defined exit handler contains errors!</tt><br>
<tt>Error in line 2: target thread died</tt><br>
<tt>Execution interrupted.</tt><br>
<br>
<br>
<tt>My actual code doesn't give any consistent behavior. Sometimes it sort of works, sometimes it generates corrupt data, and sometimes it dumps core.</tt><br>

<tt>A ha, you've describe my problem (and also the solution I found). I have exit handlers in all the threads, and I get inconsistent behavior. I wound up overriding exit to get things to exit in a defined manner.</tt><br>
<br>
<tt>It was in the process of trying to reduce it down to a simple test case that I found the problem (described above) on WinXP with just a single exit handler. Now, perhaps that's an real problem of some sort also, but it sounds like I need to continue overriding "exit" to get the desired behavior in the real codebase.</tt><br>
