It adds X-Kolab-Scheduling-Message: headers
and will to automatic invitation handling.

Basically yes, so you can try.

Obvisously this depends on your machine,
but it should not freeze the machine for 5 minutes
as only one email needs to be marked.
Technically it might be transfered in chunks, 
but it should not process them all at once.
Also kolabmailboxfilter pretty early sees if
the email contants text/calendar and will let it through
without much processing.

Are you sure you do not have the amavids and spamassassin
running in between? (Though also they should scan the message
in chunks.)
How do you do the alias?
