[VT-84] Reduction of memory footprint

Presently on my system (Archlinux/xterm/zsh) with the latest version of VIT, with 80 tasks in the pending queue. Here is what htop shows:

Process VIRT RES

VIT 81 53 mutt 85 8 newsbeuter 278 5 elinks 79 16
All the numbers are in MB. This comparison is not fair and the numbers would vary depending on the data the respective program is working on. However, I think that the fact the resident memory usage of VIT is so high points to a problem.

Other observations:

Memory size does not increase over time.
Memory size does not vary much with the size of the task database.

Please treat this more as an observation than a concrete suggestion for improvement.

Thanks for writing this up Devendra. That indeed seems like a lot of memory, especially for 80 pending tasks. It would be nice to at least figure out why this happen. It's probable that a fix would require significant surgery; but sometimes these issues can be one-line fixes.

I have a 'res' of 30M when viewing the next report, which has 742 tasks. Thus there is a mystery of how 10x more pending tasks leads to half of the memory.

I would be curious to know what other users report, if anyone comes across this bug. What is your memory usage? How many pending tasks do you have?
