[XCache] web-optimizator cold boot issue using Xcache (instead of file cache)

[GoogleCodeExporter]

Operating Environment:
---------------------
OS:              Linux Fedora 14 64-bit
HTTP:            Nginx version: nginx/0.9.3  (No Apache at all!)
PHP:             PHP-FPM; PHP 5.3.4 (fpm-fcgi)  Using via Nginx with 
"fastcgi_pass")
CMS:             Wordpress SVN = 3.1-beta2-17056
DNS (Public):    NSD version 3.2.6
Web-optimizator: 1.4.0b [SVN Release = r2865]

Using xcache V1.3.1

After a reboot, I run http://www.webpagetest.org/ (note that at this stage I 
have NOT run the web-optimizator [Refresh Cache] option - via the admin CP.

The very first instance of a page test with http://www.webpagetest.org/
results in this (next few lines below):

Once this initial [cold boot] pass is processed; - all further http page tests 
show "no problems"

If I switch web-optimizator to using a FILE CACHE (and not xcache) there is no 
cold boot problem.

It makes sense to me that Xcache loses all cache data on a reboot, and therefor 
we may need a [web-optimizator] initial cold start process to prepare the 
xcache (a once-only event)

XCache cache doesn't related to wo.static.php cache / functionality. Please 
provide info if this issue is reproducable
