I think commit message get my idea backwards:

WITHOUT fallback code I get only black screen on screencapture. It surely
fast but not that I need ..

so added code ADDS fallback in case shm capture does not work (on NetBSD or
in general).

So it hardly faster, more like working where it was failing before.
