Before I can accept it, I need to understand the reason for it. Previously counter_example.c did call close() before returning, but as David Laight pointed out, we removed it for being redundant when the kernel closes file descriptors on exit, as well as possibly changing errno before perror() and strerror() are called. Is this patch made to address a particular bug you have discovered? I would like to document the rationale for this change in the commit message so we properly understand the reason for calling close() here. Sincerely, William Breathitt Gray
