On battery-powered -SBCs and mobile devices this can cause serious and unnecessary power -drain; this has been observed on the Raspberry Pi and sporadically on -particular Android phone hardware. There are at least two reasons it -can happen; one is defective select(2) device-driver hooks that return -a data-ready when they shouldn't, the other is tty layers that return -data in single characters or small packets even when it's arriving in -packet-sized chunks. GPSD with buzzkill=yes watches the incoming data -rate from all devices and adaptively inserts delays in the main loop -if it thinks it sees buzzing. This logic is routed around if all -devices have types that never require delays, notably pseudo-ttys and -UDP packet streams. - == Port and toolchain testing == 'scons check' will run a comprehensive regression-test suite.
