Tcl Source Code

Hi,
       I have found a memory leak problem while using 
the TCL thread package. The Tcl version is 8.4.13 and 
Thread version is 2.6.2. I have also attached a sample 
script to support my findings. The sample script 
creates & releases 5 threads for 14 times . For each 
time , the memory of the tclsh process increases by 
700 kb(avg). I have traced the memory through Windows 
Task Manager. 

please forgive me if I had done anything wrong.

OS version : windows 2000

Thanks in Advance.

In the sample script which had been attached, I had used 
the API ::thread::release to release the Tthraed. 

please let me know if the Sample Script requires any other 
steps to free the Thread.

This is no leak. It is the fact that you are posting async scripts to a thread
which has already exited. Such are kept in the Tcl event queue and remain
stucked there forever. For such cases I have made the "reserve/release" 
wrappers. So you basically reserve the thread when you need it and then 
release it when not (the last releaser garbage-collects the thread). This way
you are sure the thread will not be destroyed by somebody else until you
are using it.
