Mousepad Becomes Slower and Uses High Memory Over Time
I usually have several mousepad windows open for tiny note-taking and clipboard-buffering purposes. Typically I might have a half dozen windows open, each with only a few lines of text (e.g. a citation or command being copied). These are all untitled documents that are never saved, and I rarely get down to zero windows left.
After weeks or months of use, memory usage becomes gratuitous, and the application starts to have odd delays. A newly opened mousepad process shows 47 M, but the long-running one before that had gotten up to 444 M, with only a few open windows and hardly a dozen lines of text between them. I think 50 MB for the default plain text editor is costly enough, but having to save and exit everything periodically to reclaim half a gig is pretty unpleasant.
Additionally, the windows start to lock up with long use. I frequently open and close windows for small snippets of text (e.g. removing formatting from HTML, etc). Closing these windows without saving freezes for increasingly long periods of time until the program is restarted. I do not think it is unreasonable that exiting a text editor without saving should be instantaneous, every time.
