Allow a select() call to return without inspecting the state of all selected file descriptors when at least one selected event is satisfied. This allows the accelerated select() call to avoid a system call when accelerated sockets are 'ready', and can increase performance substantially.
This option changes the semantics of select(), and as such could cause applications to misbehave. It effectively gives priority to accelerated sockets over non-accelerated sockets and other file descriptors. In practice a vast majority of applications work fine with this option.
