It is normal to expect the full tree to be in a completely sync'ed state
and I see this as a way to have that not happen. As a result I see this
option as dangerous and do not support it being merged.

FYI we are moving to waf and the sooner we can get the doco sorted and
4.11 released the sooner we have the waf work moved to the master repo
and branch. On fast hardware a BSP can build in under 30 seconds.

Have you tried the sb-bootstrap tool in the RSB?

It can do the same and better on a multi-core machine for a full bootstrap.
