I tested this patch, along with Mattias' patch posted earlier, on two
machines.
On a reasonably fast machine (AMD Ryzen 3 3200G with 16 GB RAM), there
is a marked improvement in visiting and scrolling the header files
in the linux kernel tree. The complete lockups that happened earlier
did not happen.
I also tested the patches on a Chromebook (Intel Celeron N2840 with 4GB
RAM), which is similar to the machine in the original report.
Unfortunately, the behavior was still bad, with lockups and freezing.
I tried both c-mode and c++-mode with font-lock-maximum-decoration set
to 2.
