#97 jUploader causes hard Linux swapping

[Ignat Alexeyenko]

jUploader swappes hard when RAM is free (about 2-4 Gb of SWAP is used).
Particularly issue is reproducible on uploading large photo sets (about 250 images, 5 mb per image).

Seems to be related to jUploadr window re-size and/or changing selection of images that are currently are uploaded.
