I didn't know of that feature. I've changed the code as you suggested.
Though the delay introduced here is hardly noticeable, afaics.
Please see the fixed patch attached.

By the way, about viewing huge tables: a user would feel comfortable
if he could setup the default limit for LIMIT clause in "Edit data"
windows. Currently the user willing to see some table's data has first
to notice it's rowcount and (if it is huge) instead of pressing "View
data..." toobar button has to choose "View Data"->"View Top/Last 100
Rows" from the table's context menu. Such effort is boring and takes
time, especially when the user just wants to quickly see some sample
data to "feel" the table's essence.

I'd suggest adding a setting in Options dialogue, say "Default rows
limit", defaulting itself to "No limit" to retain current behaviour.
Please let me know if it is worth trying to implement this proposal.
