slurpd private replication file trim question

["Arredondo, Tomas" <tArredondo@unispherenetworks.com>]

Looking at current slurpd implementation and I'm wondering how it
is that slurpd's private copy (ie. /usr/tmp/replica/slurpd.replog) 
of the replication log gets truncated?  It seems to use:

slurp.h:    int  (*rq_needtrim) LDAP_P(( Rq * )); /* see if queue needs
trimming */

So is it when a new job comes in to the slapd replog slurpd reads it into
it's queue and enventually if this queue is big enough then the slurpd
queue get's trimmed?

Any info is appreciated. 

Thanks,
Tomas
