TODO: possible cb aliasing?
- mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
- (ecb) support m68k, m88k and sh (patch by Miod Vallat).
@ -20,6 +21,8 @@ TODO: document portbaility requirements for atomic pointer access
- in the absence of autoconf, do not use the clock syscall
on glibc >= 2.17 (avoids the syscall AND -lrt on systems
doing clock_gettime in userspace).
- ensure extern "C" function pointers are used for externally-visible
loop callbacks (not watcher callbacks yet).

When the first watcher gets started will libev actually register something
with the kernel (thus it coexists with your own signal handlers as long as
you don't register any with libev for the same signal).
Only after the first watcher for a signal is started will libev actually
register something with the kernel. It thus coexists with your own signal
