FWIW:

I tried that in JEdit (a Java editor having pascal syntax highlighting
using the swing toolkit). It appears that:

- I had to increase the java heap size to get that file loaded (in a
session having 15 or so other files, some small, some big) from 32MB to
64 MB - other programs would not have this limit but suck in system
memory at will

- loading the file took some time (~1-3 seconds) amongst all other files

- when hitting CTRL-Down the first time the CPU usage goes up a
noticable step and a short pause occured (~2s)

- when browsing around by keyboard after the first move to the eof I did
*not* note any slow down or extraordinary load

- when scrolling the file using mouse and scrollbar the cpu load does go
up, but it works without delay

Concluding I'd say JEdit handles this file without problems.
