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...
