Even that is not enough. Apparently tv_sec can be <0 too:
Cannot set scheduling timer, errno=22, v.s=-1, v.us=1000
Presumable, usec was set to 1,000 by my hack. But the seconds were negative
too! This crash is rarer than the one where just the usec value is negative.
Here's my new hacked fix:
if ( (itimer.it_value.tv_usec<0) ||
(itimer.it_value.tv_sec<0) )
{
itimer.it_value.tv_usec=1000;
itimer.it_value.tv_sec=0;
}
