@pavelsavara please take a look

[vargaz]

Is this reproducible ?

[lewing]

it appears to be across multiple runtime-extra-platform runs last test is ConstructorTests_SyncStream.NonPublicCtors_NotSupported in all the ones I've looked at

[pavelsavara]

Chrome log shows charmap problem again, after running too long.
ERROR executor(733) _execute_command_in_container Exception: 'charmap' codec can't encode characters in position 339794-339795: character maps to <undefined>

V8 is just slow, no ?
