Hi,

I am testing the support of dynamic array in the recent base 3.14.12.6-rc1.
Using a normal pcaspy application, which updates ~15 Hz. It repeatedly gets into a deadlock state.

The analysis has been put up here
https://github.com/paulscherrerinstitute/pcaspy/issues/29

The solution could be reversing the lock order during casEventSys::process. But it does not seem to be easy,
because the chain of calls involved.
