Vitalium: Crash when resynthesizing a preset to a wavetable. #116

Some combinations of settings in the synth can cause Vitalium to crash when you attempt to re-synthesize a preset into a wavetable. I do not know what conditions can cause this but I do have a patch that consistently reproduces the issue.

Steps to reproduce:

Load the attached patch into Vitalium.
Right click on OSC 1's waveform.
Resynthesize the preset into a wavetable.
Vitalium should crash.

Turns out the issue is in rtkit rather than vitalium. rtkit is killing any process that is busy for too long, and vitalium is busy for just enough to cause it to be an issue.
