Description
There are plugins which depends on other plugins, e.g. Processing provider plugins needs Processing plugin. Plugin Manager incorrectly handles this case. It seems that plugin unloading does not take in account dependencies between plugins, unload happens in alphabetical order. As result, during unload Processing plugin unloaded, while other plugins that import its modules still there. This may cause hangs or crashes depending on user actions.
Processing should be unloaded only after unloading all its provider plugins, or maybe unloaded in the end. This may also affect other cases when one plugin imports packages from another.

The real issue is that it currently is impossible to define dependencies for python plugins (either on "usual" python modules or on other python plugins). With dependencies specified, loading/unloading and installation/removal of plugins would work much better.
