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?
