Hm - 18 sec on my linux laptop and (a new) ssd. [I wonder why the difference]

wrt es - perhaps the PATHs are longer [and they mostly point to nfs
software] and thats affecting the run time. But I've seen multiple
minutes spent on etags on various machines..

When we added these defaults - primary 'repo' users were
developrs. But now we want big chunk of our users to use repos. And
also for ourselves we are now switching between branches - and these
files are generated more frequently. So those initial assumptions
[when we made these things default] are not really valid anymore..
