It shouldn't happen in a single session--session id remains same for
the single session unless:
1. Crawler is returning and caching in multiple run
2. You have used session_regenerate_id()
3. There are random absoulte links poining in from your site to your
site (instead of relative links)

It doesn't seem to strip session id as I thought. If your site
contents doesn't rely on session (for non-members), you may safely turn
off trans sid

--even you can selectively turn off only for the crawler by sniffing
user agent string and or IP.
But, if your site depends on session (for non-members and hence
crawler) and you'd like to enable session for crawler, but doesn't want
the trans sid, you need to go for some other hack. If that is your
situation, I may help you with the hack.
