[distcc] [Fwd: "Busy" waiting when using distcc/ssh (and SMP question)]

[Marcelo Matus]

it seems the timeout is comming from the io.c file:

-------------- io.c ----

....
const int timeout = 15;          /* seconds */
 
 
/**
 * @todo Perhaps only apply the timeout for initial connections, not when
 * doing regular IO.
 **/
.........

------------- io.c ----

the current timeout is too short for large compilations. If I use 150s, then
I have no problems. But, as the @todo says, maybe it is better
to have different timeouts for the initial connection
and the compilation.
