[ECOS] ecosconfig does not terminate

[Koeller, T.]

Hi,

I have been encountering a problem with the ecosconfig command line
tool under Linux recently. I built and installed it on my Linux system
(kernel 2.4.18, glibc 2.2.5, tcl/tk 8.3.4). The tool appears to work
normally, but after finishing its task it does not exit and has to be
aborted by hitting Control-C. The process list shows the following
entries:

  440  ?  S    0:00 ecosconfig list
  441  ?  Z    0:00 (ecosconfig <zombie>)

It seems that ecosconfig fails to properly collect the exit status of
its child processes (or threads). When executing ecosconfig under
GDB control, the problem does not show. I did not notice this
behavior with any other program on my system so far.

Btw., ecosconfig is not the kind of program you would expect to use
multi-threading, so I was quite surprised to find that it actually does.
