 I had made some measurements for non-DOLT and DOLT case for the
 current libX11 case.  Here are the results of ministat spawned
 for data from 10 compilation cycles with DOLT and without DOLT:
 (fully warmed disk cache, almost zero activity on the machine,
 all resources are dedicated to the port building):

 I'd say that 45 seconds (24.5%) speedup worth some patching.
 
 Any thoughts 'bout this?
