Right; for instance failing to unlock a mutex, or roll
back a transaction, aren't resource leaks.
Yes it is. A mutex held is also a ressource, and so is a transaction.
Both should be wrapped in a class having appropriate destructor
You have to unwind EVERYTHING, no matter how small it is.
Otherwise, sooner or later your box will run out of steam.
You have to unwind everything in any language. By unwinding it in the
destructor you only write it once and you dont have to have have
special code for exceptions. Contrast this to Java: here you need the
code explicitly present in every function using the feature.
