It solves hard crashes during DNS lookups by wasting a few kilobytes of RAM. Seems like a fine solution to me. The memory leak only occurs in circumstances where the program would've crashed or started messing with random memory anyway. A proper solution would be to either nuke put/setenv() in the C standard library or redesign the *env() calls entirely, but that would break existing programs.
