I am experiencing some gst-launch lockups from time to time. I will try to
give a quick overview of the issue in case someone may know something about
this, and I can provide more detail if needed.
Basically, it seems like there may be a race condition with EOS and SIGUSR2.
When the SIGUSR2 signal is delivered to a pipeline that was transitioning
due to EOS, I see the indication that the SIGUSR2 was caught, but no further
info regarding taking the pipeline to NULL.
After this occurs, a reboot of the system is required to run a new pipeline.
