Comment # 2 on bug 13211 from 
In the meantime I have reviewed extcap-spawn.c and its usage in dumpcap.c on
trunk.

I think what changed compared with 2.1.0 is the handling of stdout/stderr of
the spawned process.

And that is perhaps what creates the problems in my specific case: My extcap
plugin does print a lot of info to stderr. Perhaps this results in the timeout
error - because windows buffer for this is too small and this blocks my extcap
plugin somehow.

I will try to write to a file instead of stderr instead and see if it solves
the problem.
