Some babysitting needs to be part of the core push protocol; anything else would be prone to race conditions in a multiuser setting, esp. when people use different porcelains.

At minimum, you'd send the old branch head with the new one, and let the server not overwrite it if it changed in the meantime.

Then, you'd kill porcelain writers who don't verify that the old head is a(n indirect) parent of the new one. ;-)
