test failure: t2801-top-cmd.t 16 - flux-top can call itself recursively

[chu11]

everyonce in awhile when i run make -j16 check this test fails. I assume something racy, but the cause escapes me.

test_expect_success NO_CHAIN_LINT 'flux-top can call itself recursively' '
	SHELL=/bin/sh &&
	flux jobs &&
	flux proxy $(cat jobid2) flux jobs -c1 -no {id} >expected.id &&
	cat <<-EOF >recurse.in &&
	{ "version": 2 }
	[0.5, "i", "j"]
	[0.55, "i", "j"]
	[0.60, "i", "j"]
	[0.65, "i", "k"]
	[0.70, "i", "\n"]
	[1.00, "i", "q"]
	[1.10, "i", "q"]
	EOF
	$runpty -o recurse.log --input=recurse.in flux top &&
	grep -q $(echo $(cat expected.id) | sed "s/ƒ//") recurse.log
'

Edit: side note, tests that occasionally fail but have a -t 30 or some similar timeout, its easy to just accept the failure. But in this test I can't tell if a timeout would be reasonable.

taking a little time to learn about this test, I'm guessing the race / error is the timestamps in the first field of the inputs above. The 1/10th or 1/20th of a second between inputs might not be a large enough time if the rpcs flux top is performing internally are too slow. We don't see this much, but if we begin to see it more, increasing those timestamps might be worthwhile, like perhaps .25 seconds between inputs.

Edit: I guess its also possible the very first command done at 0.5 seconds in could be too early?
