I didn't read all of the file, but I checked the basic stuff, and it
seems to be fine.  It also built and didn't immediately crash Emacs, but
I don't think I know how to use xwidgets (I also had to fake a pkgconfig
file for some reason, and try three distros to get it to work at
all...)

No guarantees, but I pushed something.  I had to copy out of a docker
container so hopefully made the same changes on scratch/igc.

I'd be very interested to hear whether this survives some GC cycles (M-x
igc-stats; then hit "c" a few times) when xwidgets are in use.  If it
does, we can close this bug.
