I've been experimenting with integrating tclblend into aolserver, and
after looking at the tclblend code, I'm a little puzzled about
something. In javaCmd.c the variable java declared as type JavaInfo
and currentEnv are declared as global variables, yet I would think
that these two variables wou

After moving back to the u.s., I've started looking into integrating
tclblend into aolserver/nsjava again. Last night I checked out the cvs
sources from the cvs ajuba contract branch, and started to compare it
to version 1.2.6.
I'm curious about the JavaInfo structure in javaCmd.c. When I

Last weekend I ran the merged tclblend/aolserver combination using
apache-bench to make concurrent accesses of multiple urls, and I
noticed that the memory size was growing over time. I think this is
probably due in part to the java info cache not being cleaned up. It

I was never able to get Tcl_CreateThreadExitHandler to work for either
the TclThreadCleanup or the JavaCacheCleanup routines. As a
work-around I decided to call both of these cleanup routines at the
end of the JavaInterpDeleted function. I've run this setup under
load, and other than leaking me

I've been investigating the thread cleanup, and it appears that thread
cleanup handlers created with Tcl_CreateThreadExitHandler are only
called when tcl is shutting down. This is true at least for tcl8.3.2.
I haven't looked at tcl8.4.
There is an experimental tcl thread interface in tcl8.3.2 th
