Hello Dario,

The freertos provides an interface to its scheduling internals like `vTaskSwitchContext` and `xTaskIncrementTick()`, which should be called by the platform-specific code. I thought it is possible to alternate scheduling behavior calling those interfaces differently.
Though, on the second thought, it would not provide enough freedom to build something really different.

OK, will look through it a bit later.
