Measures if there is backpressure on an Akka Stream at the given stage.
When an Akka Stream doesn't perform as intended, it is difficult to tell where the bottleneck is, since all stages operate at the same rate (see e.g. here ).
So when things are not fast as expected, this pressure gauge can help you to narrow down on the slow stage. Imagine

This a collection of notes and files used in my quest to create "Reboot to Windows" and "Reboot to Linux" scripts (and desktop shortcuts) for Linux and Windows respectively that automatically reboot my system and instruct rEFInd to auto-select the appropriate OS entry.
The key for achieving this is to modify the EFI Variable PreviousBoot with GUID 36d08fa7-cf0b-42f5-8f14-68df73ed3740, which rEFInd uses to store the last entry selected in the menu and, if using the + default entry, will be used to select the default OS. By doing this, we trick rEFInd into booting the OS we choose without having to be physically there to press the keyboard.
