I don't know how useful this test is, but I thought I would share the test description and results in case the rosegarden developers find it of some use as a verification of Thorn's stability.
What I did was to record (MIDI) about 42 bars (in the default 120 BPM) from a keyboard - just improvising, nothing very complex (I'm not much of a keyboardist), but with some rather fast note sequences to test real-time playback accuracy. Then I instructed rosegarden to loop the entire sequence and then hit play. I then let it run for a while (a couple hours, I think), listening some of the time and verified that each repetition I heard was accurate. Then I left for my trip to Missouri. When I got back, rosegarden was still executing the loop, as instructed, and when I turned my synth back on and listened to it, it was still being played accurately, as before. I left on Friday (Jan 15) and got back Tuesday night (Jan 19) and didn't pay attention to the RG process until Wednesday. I just hit the stop button a little while ago. I think what this shows is that Rosegarden, at least in this situation, can run for days, producing an accurate playback, without any problems, including showing no signs of a memory leak nor of using constantly increasing CPU resources. (After stopping the loop, RG shows up in top as: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 26393 jtc 20 0 231m 111m 86m S 8.2 3.5 1037:10 rosegarden and I noticed only minimal slowdown of other programs [mail, browser, grep, etc.] while the loop was executing - i.e., system performance remained acceptable.
