Just to be precise, it's not always wrong to skip freeing allocated memory. It depends on how long your process runs. If it runs nonstop or for long periods of time, then memory leaks will leads to crashes, but what in cases when process runs for about 1-10s and is quite small? Even if there will be multiple leaks, it won't leads to crash or instability, after termination of proces, OS will clean it up anyway.

BTW it's not my thesis, I saw this in one of popular open source projects and I must agree.
