I don't think so (no 100% sure, but almost). Maybe Geanyprj does
something every <time> seconds, and does more work if tags have changed?
(easy enough ti check I guess) ...don't know. A talk with Yura to figure
out from where the lag comes would be useful I think :)

Actually I set 250ms quite arbitrary after the performances on my
computer. Something like "100ms is OK for me, let's add a x1.5 factor
for older machines not to lag... OK, 250ms looks good" :D
