Unfortunately a long time ago I decided that a delay of 0.0
would specify that the lib should wait for ever in ca_pend_xxx(). 
Since there are applications that take advantage of this feature 
(that would break if this behaviour was changed) we are unable to 
implement what now appears to be the obvious solution (let a delay 
of zero specify a poll).

However there is nothing stopping us from creating a new entry point
(or a constant indicating a poll).
