I don't see any reason to wait. Remember, we don't support 
backward/forward binary compatibility for binaries compiled for -CURRENT 
anyway. The only reason for this bump is to allow binaries compiled for 
-STABLE to run on -CURRENT, which is not currently possible in the case 
when binary uses pthreads lib.
