Well I just noticed this:

SHA-1: 29cc68f6723eb4e9a0f29e82c87187307d041fdd

* Start daemon with --daemon
Build using daemon with --daemon
Stom daemon with --daemon

To test daemon use test/daemon_test.py

And if I understand correctly what this is doing, that this is a deamonizeable version of bb which effectively removes any delay before actual building (assuming a previous instance has been loaded), then this is greater motivation for us to switch to the python port.  Am I understanding this correctly? And if so is the python port needed to make this work? Is this going to be merged into master at some point and when?

Thanks,

Chris
