Description
In simulator, when `CONFIG_SIM_WALLTIME_SIGNAL` is enabled, any call to `usleep()` blocks indefinitely and never returns.
I have confirmed that the "tick" signal is delivered correctly and that `g_system_timer` is advancing.
However, when the time passes, the sleeping task is never woken-up.
