This is described in Peter Gutmann's paper on CSPRNG (there is a link
somewhere at www.gnupg.org).  Actually he was kind enough to donate
his code from Cryptlib by dual-licensing it under the GPL.

Well, there is no such protection.  The only way to do it is by
writing a device driver which seems to be the only way to lock memory
from swapping.  Given all the vulnerabilities of Windows I don't think
that this is a high priority task.  soundcode.com has such a device
driver but it is not free software so I have not added support for it
into GnuPG. If someone wants to write a free driver I will defintely
add the required support into GnuPG.
