Description

[error]   x warn on cpu starvation
Warning: error]     doesn't contain '[WARNING] Your app's responsiveness' (IOAppSpec.scala:211)

I think we just cut off stderr a bit too early.

Research direction

Start with IOAppSpec.scala around line 211 and inspect how the starvation test captures stderr and determines when to stop reading it. Run the “warn on cpu starvation” test and adjust the cutoff so the responsiveness warning is observed reliably; done means the test passes without intermittent missing-warning failures.
