        Low memory... Try with 256k or 512k RAM.

        It's nop swapping. It's buffer and inode flushing and
/dev/console access.
        Yeah, it's not very nice. Sometime in the future I will work on
it.

        Hum... I think you found a bug. :)

        Try loading more two or three times. See if the error persists.

        It's not a bug. It's a wrong behaviour. I never noticed this.
        Can you give me more info (in private) about your Sony? I think
I'll send you a modified UZIX version for discovering the problem...

> By the way: I noticed that Suspending a process with CTRL-Z doesn't work yet.

        No. And also, CONTROL+C stop all background processes.
        Things to work on in the future... :)
 
> Another note: top is VERY slow on a 128kB MSX2... Swapping?

        How "slow"? For updates? Or displaying lines? Change the update
delay with s key. The disk access that delays the display is the same I
explained above.
