okular memory consumption

SUMMARY
***
Okular consumes an enormous amount of Memory (it reached over 1Gb today).
I got the same tab list opened (and loaded) over the weeks (even months): it
consists of 7 or 8 tabs the size of each is in range 4 to 17 Mb (there’s no
large files).
***


STEPS TO REPRODUCE
1. Open up to 10 files with average size of 10Mb each. 
2. Suspend session. Resume. (few cycles during a day or couple of days)
3. Observe how Okular consumes Memory in System monitor.

OBSERVED RESULT
an enormous amount of Memory

EXPECTED RESULT
adequate amount of Memory
