Barring a kernel bug, there should be no memory leaks from exit().  _exit() is
the ultimate process cleanup tool.  Calling free() won't necessarily return
the memory allocated by malloc() to the kernel.

Unless you have a good reason to actually tear down everything, just print a
message and call exit on error in little helpers like this.
