The current approach to I/O in libprocess, with a single thread performing both the I/O polling and I/O syscalls, cannot keep up with the I/O load on massive scale mesos clusters (which use libev rather than libevent).
Libev supports running multiple loops within a process, so it is possible to support a customizable number of I/O threads in libprocess, at least for libev to start.
