I just checked that in a few days ago. Check out webapi.txt .. it's most
easily expressed as a request body to PUT /uri?t=mkdir . And a quick
test suggests it's 30% faster than mkdir+set_children (it goes from 3
roundtrips to 1).

The DIR2:CHK: creation function will be PUT /uri?t=mkdir&immutable=true
, I think.

cheers,
