------- Additional Comments from Adrian Bunk <bunk at stusta.de>
Dolt only made a noticable difference with old libtool versions.
With libtool 2.2.10, the speed difference is < 5% in "make -j8"
builds I tried.

"time make -j8" output of 3 runs before the patch and 3 runs with this patch on
an Intel 
i7-860 with 8 GB of RAM:

With dolt:

real	8m48.871s
user	63m5.526s
sys	4m14.357s

real	8m43.389s
user	63m14.902s
sys	4m15.006s

real	8m44.677s
user	63m15.848s
sys	4m14.686s


Without dolt:

real	9m8.344s
user	64m31.824s
sys	4m24.658s

real	9m8.492s
user	64m30.652s
sys	4m24.363s

real	9m6.837s
user	64m32.277s
sys	4m24.979s


The fabulous speed increase in the email linked from
https://bugs.webkit.org/show_bug.cgi?id=19395#c3 were against libtool 1.5 that
was already obsolete of the time of that email.
