Memory leaks are common in applications that have not been
sufficiently tested and debugged to eliminate them.  It's a
sorry state of affairs when such an application is in
mission-critical use.

In general, the OS has no way to know when memory is in use
by mistake (while the app is still running).  Regardless of
whether a platform performs garbage collection (e.g. Java),
it's not only possible but common for memory leaks to occur.

Of course not.  It's embarrassing.
