I'll admit to not really knowing what I'm talking about here, but on 
first intuition, What about either btrfs filesystem sync calls, or 
mounting with the synctime (don't have time to look up the specific 
option ATM) mount option?  Normal sync is 30 seconds, but the mount 
option can be used to make that 5 seconds or whatever.  And I don't know 
whether btrfs filesystem sync is synchronous or not.

But that might help reduce it below 30 and 45 seconds, anyway, even if 
some sleep is still required.
