I realize the intent of the OLPC project is to make "booting the
system" as quick as possible. There is one situation for which
introducing a deliberate __delay__ might be beneficial:
It appears the XO is testing its front panel buttons as soon as it
starts running. If an individual used his strongest finger to push
the (recessed) 'power on' button, there does not seem to be enough
time for that individual to transfer that same finger to one of the
other front panel buttons. Those other buttons are small; if the
individual does not have enough dexterity in his other fingers, the
"which buttons were pressed" indication as picked up by the XO may
be different from what the individual wanted to convey.
Let me suggest the XO pause a half second following a 'power on', to
allow a feeble user time to re-position his fingers (from the task
of turning on the XO, to the task of indicating "what is special
about this boot").
