RE: [ros-dev] TEB spacing

[Hartmut Birr]

Hi,    

I've still more problems with the modifications in the virtual memory
functions. My test case is ctm from rosapps. It shows the cpu time and
memory usage of the processes. While waiting for a keyboard event, ctm
(kernel32) destroys and creates every 100ms a new  thread. It seems, that
the memory (teb, stack, ...) isn't freed. The thread itself is destroyed. Ps
shows always two threads for ctm.
