Flaky test TestDSA

First time I've seen a failure since we fixed the first round of these:

@majestrate interested in taking a look?

Saw the same thing when randomly checking test cases. Forgot to log it at the time, so I ran a loop to see if it would happen again and it did... Not sure what it means yet but I can say I've seen it as well.

pew:$ for i in {1..50}; do go test -timeout 30s -run ^TestDSA$; done
