devito setup.py installs top-level package just named 'examples' into site-packages

Setting `coefficents=symbolic` on a function with `staggered` and not specifying stencil coefficients results in derivatives defaulting to incorrect values. It appears that specifying coefficients does not change them from this...

The same Operator can be `.apply` concurrently by different threads, but there are certain non-functional objects attached to, or used by, it that aren't thread-safe yet: * The Profiler's `py_timers`...

A python script running a TTI RTM for only one shot with pyrevolve (https://sesibahia-my.sharepoint.com/:u:/g/personal/oscar_ladino_fieb_org_br/EWpX_VT4U3lCqdAArLVaGKABe9oysSb0KKRDlqIyL1XpwA?e=TgKdL4) runs fine for a period of time before crashing with the following error: ``` File "/home/oscarm/.conda/envs/devito-v4.2.2/lib/python3.8/site-packages/pytools/prefork.py",...
