Supporting concurrent reads on a single raster map would make the code
significantly more complex. Concurrent writes would be even worse
unless compression was disabled.

In 7.0, concurrent reads from or writes to different raster maps
should work (in 6.x, it's unsafe). This might allow for significant
parallelism in e.g. r.series, which often has a large number of input
maps.
