monero-wallet-cli: hang on exit in readline code (#2117)
readline_buffer: fix start/stop threads being starved by process
process could run for quite some time re-acquiring the process
lock, leaving start/stop starving. Yielding after unlock in
process is much better but doesn't seem to be enough to reliably
yield, so we sleep for a millisecond, which should be transparent
for user input anyway.
