Exim4: disablign delay in flushing mail queues

[Micha Feigin <michf@post.tau.ac.il>]

When I use fetchmail to import my mail through exim4 it only flushes the first
few messages imidiatly and the rest are delayed quite a bit unless I do 
/etc/init.d/exim4 restart.
Any way to disable this behaviour with exim?
