this raises a question in me. with the 2.4 version of exiscan, being
an external solution, mails can come in at any rate, they will be
queued and exiscan will scan them at a rate/whatever as it is
configured in exiscan (childs and the like).

with v4 of exiscan, do i get it right that the scanner will be
launched on every incoming message, right when the message is coming
in ? my point is, using exiscanv4 requires a whole different approach
wrt hardware sizes of mailservers, as one can't limit the number of
running scanner processes (except for a "hard" limit in exim itself,
accepting this-and-that many incoming connections altogether), no ?

or am i getting the story wrong someplace ?
