Thanks, this looks like a reasonable thing to do. |
Reduces the CPU usage by the PPP thread by sleeping for one tick if there was nothing to read; preventing the loop using 100% CPU when the read operation has a zero timeout and immediately returns. Signed-off-by: Daniël van de Giessen <[email protected]>
