GCJ and Boehm GC "Incremental Collection"

- Subject: GCJ and Boehm GC "Incremental Collection"
Hello:
We are running a port of GCJ 3.3 w/Boehm GC 6.2 on Windows CE v. 4.2
(Xscale processor). As this is a reasonably low-tech (i.e. CRIPPLED)
platform, we are experiencing long, disruptive delays from "world
stopped" Boehm GC.
Naturally, there is nothing "wrong" with Boehm GC.
Our challenge is to make this work as best as we can. What is the
"Incremental GC" feature of Boehm? Does it do what the name
tantalizingly suggests - incremental collection without "world
stopping"? If so, this could really help us a lot. If "incremental GC"
could help us, what would be needed to use it from GCJ? We've done a
lot of work/hacking with GCJ/Boehm, so we're not afraid to plunge in
where others might fear to tread.
Thanks in advance,
craig vanderborgh
