Bug 290583

Version:           0.8.0 (using KDE 4.7.3) 
OS:                Linux

When I visit the page http://attasi.com/labs/picsselz/ , rekonq's virtual memory consumption with only the one tab open is extremely high. Its virtual memory is
at 1.6 GB whereas Firefox is only 0.6 GB rendering the same page.

Reproducible: Always

Steps to Reproduce:
Visit http://attasi.com/labs/picsselz/ in Rekonq and Firefox.
Use ps alx or top or some other tool to explore memory usage.

Actual Results:  
~ % ps alx | grep attasi
F   UID   PID  PPID PRI  NI    VSZ   RSS WCHAN  STAT TTY        TIME COMMAND
1  1000 12727     1  20   0 1648512 107432 -    Rl   pts/2      3:45 rekonq http://attasi.com/labs/picsselz/
0  1000 12925 12691  20   0 587628 101556 -     Rl   pts/2      0:03 /usr/local/bin/firefox http://attasi.com/labs/picsselz/

Expected Results:  
Although the real physical memory according to System Activity is about the same, VSZ (virtual memory) is really high. If you limit this rekonq will crash.

The first time I viewed this CSS animation, it crashed in in do_malloc<true> (size=<optimized out>) at wtf/FastMalloc.cpp:3635 because I set `ulimit -v 1536000`.  So I filed crash bug 290579 via DrKonqi, which was marked a dupe of another FastMalloc crash bug 289261.
