I would expect that anything which wanted to cope with missing
maps would run G_find_* before deciding to do G_open_*.


as this is a rasther big nail in the non-persistent use of
libgis, I'll ask how much of the existing code limiting us to
single use is by design and how much of it is by oversight?
Would we be fundamentally altering the design POV with this
change? (not in a practical sense, but in a design intentention
sense)

400 global variables are not an insurmountable number to slowly
chip away at IMO, just hit each libary one by one for some
years..
