There is little point using the mutex before the scheduler has started,
so I assume the reason you are doing it is because the same code runs
both before and after the scheduler is running.
I THINK that, as long as you have a block time of 0, then you SHOULD be
ok, but am going from memory of the source code and haven’t actually
tried it. Note that calling [nearly] any FreeRTOS API function before
the scheduler has started will [deliberately] leave interrupts disabled.
