ComicRack v 0.9.48 released

I actually had the feeling that ComicRack did not have major stability problems. Wow, was I wrong... After some new reports on the Forum (hint: if you have problems, post them there), I really tried to crash ComicRack. Let's say I did not have to try very hard :/

ComicRack is a rather sophisticated application with about 25 threads running concurrently. These background threads do stuff like loading and creating thumbnails, precaching pages, updating information to the files, saving the changed library back to disk, converting a batch of comics to a new format and so on. One of the goals was to write ComicRack in a non blocking way, meaning in only very rare cases there should be progress bars.

One of the things I learned is that unrar.dll from rarlabs (which ComicRack uses to open cbr files) is not very stable in multithreading conditions. And if it breaks, all sort of 2nd tier bugs surfaced.

So two days of stress tests and really pushing the limit, testing in single and multi processor conditions, i would say that the stability problems should be solved.
