The main reason for the need to erase the monitor when switching
mapsets is that some d.* modules use the current region from the WIND
file, while others use the region which is stored on the monitor.
Consequently, it's recommended that you erase the monitor whenever the
current region changes. And changing the mapset will typically change
the current region.
Maybe we should just get rid of the region which is stored on the
monitor? Although, some programs may require it; AFAICT, the point is
that each frame (in the sense of d.frame) might have a different
