The limitation is documented, and I have always been considering killing
the IDLE option upstream. Some server NOTIFY extension that is not as
limited as IDLE is, might help, but I don't know how widespread that is.
Else fetchmail would have to undergo internal restructuring and go on
wasting sockets. For large POP toasters, you can't use IDLE anyways, on
medium-sized, you might run out of file descriptors.
