Your supplied output doesn't support this assertion:

Total CPU time used since startup (up  9:06) is just under a second,
this seems pretty reasonable to me.

Resident size is just over a megabyte, this isn't wholly unreasonable.

If you're looking at that 19MB figure for virtual size, I'd direct you
to the line immediately above (for top itself):

That's curiously 19MB too isn't it? :-)  That 19MB figure is almost
certainly the overhead of loading libc, translation updates, and so on.
It could be the overhead of copy-on-write maps for relocation as well.

There's no evidence that init is taking more memory than expected or
slowing down your machine (0.99s total CPU time in over 9 hours is not
going to make any difference).

If you want to know which process is causing you issues, it's the one at
the TOP of the top output:

Have you ever, ever felt like this?
Had strange things happen?  Are you going round the twist?
