[ROOT] Multiple access to a file

Hi ROOTers,

I have a simple question. I want to run multiple different proccesses that
use ROOT 2.25-03 (yes I know it is ultra old) libraries, and these
processes will write into one single ROOT file at the same time. There are
subdirectories in the file and the processes just write into histos in
their respective subdirectories. Is this possible? Is this dangerous? If
so, why?

Thanks for all the help. If the answer turns out to be complicated, you
can point me to any other source as well.

Cheers,
