Theyre probably in a changelog somewhere, but also I am working on a new
documentation system (generated from ChucK source) which automatically
picks up new features like this. There is a prerelease version here:

Hmm, it would be nice if there was no difference. But there is a
difference, internally, and it appears that is leaking out of the
abstraction so to speak. So basically .exit() appears to terminate the
shred immediately whereas Machine.remove() waits until all shreds have
finished executing for this sample, i.e. all shreds are waiting => now. At
least that is what I am interpreting from the source code.
