Parse if there have been new mails synched to the local dir.

If you use postsynchook, there is no need for cron. Offlineimap will just
execute the provided script after it finishes its sync with IMAP server.

Depending on the number of emails you have and the type of drive (SSD? big
cache?), the 'find' command may execute faster or slower. But inotify is AFAIK
a special mechanism for notifications of filesystem events suited just for this
purpose. A program/script informs kernel that it wants to be inotified and it
will wait without any further I/O or CPU usage until the filesystem event

You can check this yourself, execute:
    inotifywait /tmp/

Until something happens in /tmp/, the program shows 0% CPU usage and not even a
single kB of memory reserved.
