print macros do not lock stdout or stderr

If a println gets separated into multiple writes, it could be interleaved with the printing of other tasks. This should be fixed at some point.
The way to do this is to use an async around Stdout and StdErr and then lock those. its not enough to use StdoutLock directly without an async mutex because then you will have deadlocks between different tasks using an async print.
