    You are likely using an exceptionally slow computer.

I am using a Lemote Yeeloong, which could well be the machine
we will recommend to the public for the coming year or more.

I just did some testing and I am obliged to modify my complaint.
It seems that the slowness is mainly in _loading_ C mode.

Visiting buffer.h, when it is the first C file I visit,
just took 20 seconds.  However, once C mode is loaded,
visiting buffer.h again is pretty fast.
