Thanks!

Just tried, and it really works. With my generational gc test code,
maximum collectgarbage("count") value is actually _higher_ (also
the TRACEMEM shows higher value), even though the resident set size,
reported by time -v is lower.

What exactly does the value of collectgarbage("count") mean?
