Re: trouble with mem sucking slave interps

I have the situation now were my application creates several slave

But as it seems deleting a slave does not mean any memory gets
freed?! This is an observation with Tcl 8.4.1 on Solaris. I will try
to setup something in ActiveTcl 8.4.9 tomorrow.

I looked into this as the application is running for a while and
soaked up more and more memory. When the final [exit] in the main
interp got called it took several minutes before the shell prompt
returned.

Is there anything I can do about it? Maybe before deleting the slave,
[unset] on all variables or something?


I'd be curious what you do, and what might be left behind.
For the most part, interps clean up after themselves (freeing
all commands and vars created).  Using 8.4.9 I ran loops of
1000 { interp delete [interp create z] } and saw no mem loss.
Note that the creation of each interp creates commands, procs,
vars, etc. in initialization.
