When a write to a pipe exceeds PIPE_BUF number of bytes, this action may be non-atomic, and thus produce unexpected and undesirable results. This is primary purpose behind which we aim to conduct all pipe I/O operations using sizes less-than-or-equal-to PIPE_BUF quantity bytes. 

A zombie process consumes resources belonging to its parent (i.e., a memory leak in the parent process is introduced by the creation of zombies).
