On fencepost.gnu.org, I get 18 to 20 seconds on that file.
I guess this also depends on the number of revision that the project
has. GDB has 36544 (if my git command was correct ;-); Emacs has
106K. And the file I was talking about, xdisp.c, has 1592 revisions
in its history, not 573 as dwarf2read.c.
So this problem is probably still in GDB's future. But it is real
nonetheless.
