Dnews doesn't use the part buffer "super space efficiently'" it does use
it "super time efficiently" , specifically it avoids fragmentation and all
reads/writes
are contiguous, this is quite important as the part buffer has to have so much
data going thru it. The down side is at any one time half of the space you
have
reserverd may not be used.
So to answer your question, items are stored in the order they arrive, when
one is complete the comlpete items are sent into dnews, thus leaving gaps
in that part of the part buffer, the gaps remain until dnews cycles right thru
your entire part buffer
Your part buffer is '306' minutes long, which is fine, you won't be loosing
any significant
amout of parts due to this.

Nope sorry, you get an hour worth of broken parts if you turn it off.
