Application Memory Leaks?

[wrldwzrd89]

If a Mac OS X application (command-line OR GUI) crashes, and therefore doesn't free any memory it may have allocated, does Mac OS X return such memory back to the free memory pool (because, for example, such allocations are part of the application's memory size), or is that memory lost in a state of being allocated but never freed? In Mac OS 9, an application crash would leak memory.

It should get returned to the system when the process is killed by the kernel. Memory leeks only normally occur when a process keeps running but does not free memory that it is no longer using.

That's encouraging. I'm glad Mac OS X is designed well enough to be immune to the kinds of problems that plagued Mac OS 9. That means that if a Classic environment application dies, taking all of Classic down with it, Mach (the Mac OS X kernel) will return all memory allocated to Classic back to the free memory pool, right? If that's true, that feature ALONE makes Classic better than a boot into Mac OS 9.
