CentOS - Feb 2019 - dont run cron.d- when cron.daily-scripts are running

EL6 context: 
cronie-1.4.4-16.el6_8.2.x86_64
cronie-anacron-1.4.4-16.el6_8.2.x86_64
crontabs-1.10-33.el6.noarch

I have some cron.d entries that execute scripts in minute intervals and I'm
wondering how could an
"official" way look like, to have a condition to not run cron.d
entries when cron.daily scripts are
running. Sure, I can hack something around file timestamps or so but that feels
not so streamlined ...

I'd really appreciate any ideas ...

Well, this is anything but elegant, but if your daily occurs at an exact hour
and minute you could write two series of per minute cron jobs (a
"before' and an "after") avoiding that minute.

run-parts doesn't look like it produces a lock, so I'd venture that the 
simplest way would be:

*/5 * * * *?? root pidof -x run-parts || your-command-here

Thats a nice solution! Pragmatic and more accurate than the path I was on.
Thanks!
