My view is that ATC is dangerous, but important in some
situations where polling is impractical. It is somewhat safer
than setjmp/siglongjmp, which is a standard, and relatively
frequently (mis?)used, feature of ANSI C and POSIX.
Note that most "production quality" database systems operate
under the presumption that the power cord can be unplugged
at any moment. Abort is somewhat less catastrophic than that...
