What happens to initramfs after boot?

OK, I did it...
I compiled an all-modules kernel and I am using udev inside my initramfs
init to find my root partition and boot the system.
It works cool... :)

It wasn't easy, and after lots of tries with klibc-1.5, I gave it up and
went to a straight glibc (2.8-20080929).

Also, sorting out modules dependencies was a $%#& (challenge :), so I just
included every freaking-existing-module-under-the-Sun into my cpio tree.
Along with a bunch of commands and glibc libraries.
That yielded a generous 30MB worth of junk to boot from.
In memory...
Still with me?
Good... :)

Now my question is:
Where do those 30MB go to after boot?
Are they released back to the pool or are they held hostage in RAM forever?

I'm dizzy and crossed-eyed reading kernel documents/messages and I just
can't come up with a straight answer.
I think I'm gonna puke depmods... :(
Does anybody know?

PS: BTW, this is an LFS installation, nothing fancy...
