No.

I Quote:
    http://developer.gnome.org/doc/API/2.0/glib/glib-The-Main-Event-Loop.html
For the following reason:
======================================================
Note that timeout functions may be delayed, due to the processing of other event 
sources. Thus they should not be relied on for precise timing. After each call 
to the timeout function, the time of the next timeout is recalculated based on 
the current time and the given interval (it does not try to 'catch up' time lost 
in delays).
======================================================

Use this function in your own loop maybe ?
