Generally a memory leak in a stand alone application is not fatal, as it gets cleaned up when the program exits.
What do you do for Server programs that are designed so they don't exit?
If you are the kind of programmer that does not design and implement code where the resources are allocated and released correctly, then I don't want anything to do with you or your code. If you don't care to clean up your leaked memory, what about your locks? Do you leave them hanging out there too? Do you leave little turds of temporary files laying around in various directories?
Leak that memory and let the program clean it up? No. Absolutely not. It's a bad habit, that leads to bugs, bugs, and more bugs.
Clean up after yourself. Yo momma don't work here no more.
