long umount time

I sometimes see excessively long umount times (40-60 s) with jffs2/nand. 
The platform is a custom at91rm9200 board running linux 2.6.10 with 
mtd snapshot from 3/28/2005. Umount is from busybox. The umount time varies
but the system is mostly idle during it unlike during mount. After a few
operations with filesystem it goes away until sometime later. Has anybody 
seen that?
