Subject: [PATCH] vmstat: Support for timestamps with '-t' & fix for '-wd'
From now the vmstat can append a timestamp to each line in the
VMSTAT and DISKSTAT mode. You can achieve that with the '-t'
switch.
The '-w' switch now works in the DISKSTAT mode too.

Subject: [PATCH] watch: Don't leak extra fds to the child
Once the write side of the pipe has been duped to stdout for the child,
the original pipefd is no longer needed, so it can be closed to avoid
leaking to the child.
The leak can easily be seen with "watch ls -l /proc/self/fd", but I
found this due to "watch lvs" diagnosing itself:
File descriptor 4 (pipe:[3163616]) leaked on lvs invocation.
