this is an easy format string attack vector which serves no purpose
that I can fathom. the commit log where it was added it also made
no mention of this, as it was done in a seemingly-unrelated feature
addition

let's say you sue tiling or some module and it wants a window by
default to maximize or fill the screen or be size XxY ... this stops
the client first having a buffer smaller (or larger) and then sizing
down rendering 2 times (one of the renders is pointless). this makes
initial buffer render/show seamless as it should be in wayland.
in case eina_init uses env vars, move it to befor setuid() so it can
detect. you normally would setuid only for a limited op and we do it
for "the rest of the running" as e_sys is fairly simple.
So yeah, I've literally used sed to replace every occurrence of
ecore_time_add() with ecore_timer_loop_add() because I'm reasonably
confident that no part of E has a legitimate need for timer based on the
exact current time.
It would be really nice if I'm not wrong. :)
The reason for this is the incredible spew of clock_gettime() calls I'm
seeing on an ARM system (that should have a vdso for gettime, but...)
This can amount to thousands of system calls per second.
