- MainLoopDelay - in milliseconds
  Set this to a non-zero value to add some CPU yielding to the main loop
- SocketSelectTimeout - in milliseconds
  Set this to a non-zero value to add some CPU yielding while waiting for
  receive data from the TCP socket

These are 2 knobs created for Fzf (FQBBS) to "to reduce the CPU usage". Their
default values are currently 0, so you'll need to set these to non-zero values
to play with each of them and see their inpact on CPU utilization and
responsiveness. I'd suggest starting with low values (e.g. 1) and experimeting
from there.
