returns a single process that matches pid, or raises Not_foundval with_pid : Core.Std.Pid.t -> Process.t option

pkill ~signal f
sends the signal to all processes for which f returns true. It
returns the list of processes that were signaled, and the resulting errors if any.val with_username_exn : string -> Process.t list

calls with_uid after looking up the user's uidval jiffies_per_second_exn : unit -> float
jiffies_per_second_exn
. A jiffy "is one tick of the system timer interrupt. It is
not an absolute time interval unit, since its duration depends on the clock interrupt
frequency of the particular hardware platform."
