excessive memory usage during SELECT DISTINCT query

[coffeegoddd]

Dolt v1.43.7

dolt clone post-no-preference/options
cd options
dolt sql -q 'SELECT DISTINCT `act_symbol` FROM `option_chain` ORDER BY `act_symbol`;'

Executing this query uses almost 80GBs of memory locally and takes a long time to complete (if it completes at all)

@jycor I think this is probably due to some loop in GMS (or possibly dolt) not checking for context cancelation
