svn commit: r207284 - head/usr.bin/gzip

Author: delphij

New Revision: 207284
URL: http://svn.freebsd.org/changeset/base/207284

Log:
  Use _exit(2) system call directly instead of using exit(3) in signal
  handler, as the latter is not guaranteed to be signal safe, and we
  do not really care about flushing the stream during SIGINT.
