Use ppoll(2) instead of poll(2). This has two benefits. Firstly,
we can use struct timespec throughout and avoid any conversion
issues which might cause jobs to fire prematurely. Secondly, it
eliminates a race condition that could delay us taking action on
SIGCHLD and SIGHUP. OK deraadt@ okan@ ratchov@

remove debug code.
I think the level of debug code in cron is excessive for a program
that has reached feature complete. If cron needs to provide more
information to the user about its operational status, I think syslog
would be more appropriate. (The debug flags also disable forking
into the background, so they aren't even that useful for debugging a
live system.)

Use standard types for wait, readdir, signals and pids.

use poll() instead of the select malloc/free dance which was used to
avoid fd_set overflows.

Back when I was young, I fixed these throughout the tree, and the world

use poll() instead of the select malloc/free dance which was used to
avoid fd_set overflows.

Back when I was young, I fixed these throughout the tree, and the world
continued on ignoring the issue... The malloc/free dance was used because
poll() was not very portable yet. Now poll() is commonplace, and we should
use this safer API.

Adapt cron and at for future large time_t and tv_sec types. These were some
of the harder programs to adapt, so let me know if problems happen.

defines instead of using custom macros. OK deraadt@ gilles@

Our crontab(1) hasn't used SIGUSR1 to signal cron in years, we now use
a Unix domain socket to trigger a reload.

If two or more changes are made withing a single second it is possible
that only the first change will be loaded due to the granularity of
st_mtime. Work around this by zeroing the saved mtime when we get
a poke on the socket from crontab or at since that means there has been
a change. Fix from Daniel Lucq.
