Yes. I mean input/output with sockets
ev_io_init (eh->getEvP(), func, sfd, flags);
ev_io_start (loop, eh->getEvP());

Sorry, it was bad example. This example works fine, becouse time
interval is still.
Next example describes the problem:
*/ / int a[3]={40,5,20};
for(int i=0;i<3;i++)
{
LocalOpcodeData *ldt = new LocalOpcodeData();
ldt->opcode=1;
ldt->opcode_param0_uint=time(NULL);
ldt->opcode_param1_int=a[i];
cerr<<"\nsetTimeout="<<a[i]<<endl;
set_timeout(cfd, i,ldt);
}*
And out is:
/setTimeout=40
setTimeout=5
setTimeout=20
localOpcode=1
bot5 timer...5
localOpcode=1
bot5 timer...20/
And the out of
/localOpcode=1
bot5 timer...5
localOpcode=1
bot5 timer...20
/happens at firs 1..3 seconds.
Timeout for 40 seconds not passed over a 2 minutes. And i do not wait
for it any more.

ok, i'll remove it.

that's also ok.

ev_loop is in different thread. Is this a problem?
