With a single combined sanitier job, we saw failures at CI of p4 tests, where the server "goes away" in the middle of tests, for apparently no reason, and I just speculated perhaps the tests taking too long may be causing an impatient server side to go away before the client side finishes its work or something. After splitting the ASan and UBSan jobs into two and ejecting a topic out of 'seen', CI started passing for the first time in several days.
So, here is what I ended up using, at least for now.

The current code is clean with these two sanitizers, and we would like to keep it that way by running the checks for any new code.
The signal of "passed with asan, but not ubsan" (or vice versa) is not that useful in practice, so it is tempting to run both santizers in a single task, but it seems to take forever, so tentatively let's try having two separate ones.
