Subject: altoslib: Flush during set_state. Don't store listener state.
X-Git-Tag: 1.6.3~2^2~9
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=59466c1c2dbf95c427c2bb52304049eaac4d124f

altoslib: Flush during set_state. Don't store listener state.

The listener state wasn't used anyways, so don't bother storing
it. Also, flush the state during set_state, which actually causes the
state to be written out.
