Consistent definition of priority levels
In the specs and the documentation of the spawn_opt family of functions there is the following definition of priority levels: Level = low | normal | high However, the process_flag/1 function in that module reads: process_flag(Flag :: priority, Level) -> OldLevel Types: Level = OldLevel = priority_level() priority_level() = low | normal | high | max This is clearly inconsistent. Change specs to use the process_level() type declaration instead of re-defining it in various places.
