Emacs W32 HEAD: Pausing on disk access

[Les Harris]

I've been tracking head and building a windows build using a
Gnuwin32/Mingw toolchain.  Sometimes, on what appears to be disk access
(visiting/saving a file, eldoc lookups, etc,) Emacs will freeze for
roughly 1-3 seconds.

Its a little sporadic (in the sense it doesn't necessarily happen on
every diskaccess) but quite consistant and frequent.

What can I do to assist in tracking down what's causing this?  Or
perhaps I am the only person seeing this and it is a local system issue?

I certainly don't see this behavior in a GNU/Linux environment.

Thank you!
