Sure...  If you control all the code, and your code has no bugs in it (so that no infinite loop occurs somewhere you didn't expect).  That's not always the case -- I certainly expect that my code has bugs and I use a fair number of external libraries which may have bugs of there own.

Since most of my task code is single threaded and numerical, and I'd plan on throwing away anything touched by a killed thread, a lot of the concerns that are brought up seem more handleable than might be the case in other applications.
