bdb backend: memp_trickle

[Eric Irrgang <erici@motown.cc.utexas.edu>]

I haven't found any mention of the BDB DB_ENV->memp_trickle method being
utilized or discussed in relation to openldap.  Is this something that is
deemed to be not worth pursuing or has it simply not yet been addressed?
Or is it being addressed and my Google skills just aren't up to par?

It seems like it could be very useful.  I see our large server grind to a
halt (really slow for a minute or two) when it suddenly decides to
checkpoint after hitting the magic number of writes.  During a big load or
update this seems like a silly unbalanced way to behave.
