It sounds like your apps need to write to an fs on flash and are blocked
on completion of the initial jffs2 gc pass, not that the cpu hogging is
blocking your apps. If so, would suggest a separate partition with a
read-only fs (CramFS, etc.) for read-only data/executables (if not
already), maybe put /tmp and /var/tmp (or whatever dirs the apps are
writing to) in a ram fs such as tmpfs, and later copy
important/persistent data to jffs2 after everything's started up...
