No, the machine is not particularly loaded. I believe the most
likely cause is "the code has a syntax error that is particularly
hard to correct"; but this is only because of partial parsing as
the entire file is syntactically correct.
I'll send you the next source file where this happens; maybe
you can reproduce.
Increasing wisi-process-time-out to more than 5 seconds does not
seem like a solution to me; parsing the entire buffer (resulting in
no syntax errors, no attempted recovery and no time-out) takes
less than that. Also, since we are only moving point in an
unmodified buffer, interactive use requires 0.1 s response time or
less. Therefore, perhaps a solution would be to /decrease/
wisi-process-time-out and automatically launch a full parse
whenever it happens; as long as the buffer remains unmodified, no
re-parsing will take place.
