187On GNU/Linux systems, EV uses the LSB 3.1 __register_atfork function
188to avoid the dependency on libpthread, and directly uses the clock_gettime
189syscall to avoid a dependency on librt.

257For example, if you run into compile problems because of missing memory
258fences (or you just want extra performance), you can tell EV to not support
259smp and threads via -DEV_NO_THREADS.
