Hi,
I have a script that is using some packages. The script is set up such that if the package it is trying to use is not installed, it will do a ``Pkg.add`` to add the package before ``using`` it. This script is triggered by a third process, and it might be triggered multiple times simultaneously, i.e. multiple instances of julia might run the same script at the same time. Therefore the second julia instance might issue the same ``Pkg.add`` command as the first instance, while the first instance is not done with the ``Pkg.add`` yet. I assume the package manager per se is not set up to handle that situation gracefully? If not, is there some package that allows me to have something like a mutex/lock between my julia processes, so that I can guard the code section that fiddles with packages and make sure only one julia instance at a time runs that code?
