My buffer is set to 1000 lines at present... which matches up with the
'seq 1000'. But if it's a one-time memory allocation delay, then
shouldn't the second run of 'seq' should be faster? It wasn't; the
"two-gear" effect was visible for every run.
Yet tonight, I'm unable to reproduce the "two-gear" effect. Such a

Well when first I reported the bug the terminal speed was really slow;
these stress tests were just attempts at reproducing that state.
For sanity's sake I'll take a break for now, maybe some abler user will
bump into it.
