Quick Look Helper problem solved! (I think)
Still chasing down why Quick Look Helper hogs the CPU, allocates a ton of memory, and slows the machine down to a crawl ... and all OK after quitting the process ...
Finally decided to call Apple, and a software specialist helped me debug the problem.
I'll go through the whole scenario, as we found some unrelated problems that you might find too.
First, ran "Verify Disk" on Macintosh HD ... and found some errors.
Did a Time Machine Backup
Ejected and disconnected all external hard drives
Rebooted in Single User mode (Cmd-S during boot)
Ran "/sbin/fsck -fy" (type in exactly as shown)
The previously noted verify disk errors were repaired (whew...)
Re-ran "/sbin/fsck -fy"
All checked out OK (Apple engineer said this fixes many of the problems they see w. slowdown).
Re-booted normally
Started Activity Monitor and Quick Look Helper was taking up about 2% CPU activity
Opened Macintosh HD in column view ... to Documents ... to a .rtf file and clicked on it
Spinning wheel for about one sec in Preview pane
Then preview pane went blank (white)
Quick Look Helper immediately went to 195% CPU activity and computer response slowed
Clicked on some other files and many showed just a spinning wheel in the Preview pane
Looked in System/Library/Quicklook and removed VMWARE FUSION QUICKLOOK.QLGENERATOR and
Pacifist qlgenerator
Rebooted .... and all functions normal ... previous files w/o preview icons displayed normally, Quick
Look Helper stayed at 1%, and dropped back to 0.0% when no keyboard activity, no slowdown,
etc...
Re-installed the Pacifist Quicklook helper file
Rebooted ... and all functions normal
So - it looks like VMWare Fusion QuickLook.qlgenerator is the culprit --- and I sent this note to
VMWare as well.
I've gone to Bootcamp as I have few Windows applications that I use, and it is pretty foolproof.
Might take another look at VMWare Fusion in the future though ... as I like the convenience ...
Hope this helps.

Hello,
Coincidently, I found a way to reproduce the panic.
I wrote a program that writes a log into a file.
As long as this log file is selected in any Finder window and my program is writing to it, the bespoken problem arises. Deselecting the file solves the issue.
I think this is a true bug in OS X! The helper seems to try to keep up with the file changes …
Best regards,
