git - Performing multiple operations simultaneously on repo -

we using google's git-repo tool our projects. our workflow make changes , merge remote , push tags.

my question is, there problem if perform multiple operations @ same time on same same repo/codeline/tree? suppose if pushing tags remote, there problem if start repo sync?

or while pushing tags if start cherry-pick new changes?

repo runs git operations under covers, shouldn't run situations data in individual projects corrupted. however, if repo tries run git operation on single project while instance of repo (or git) running git operations on same project, second 1 fail because can't lock repository. result in half of projects getting updated , other half being left behind or similar.

i'd recommend not using 2 instances of repo on same sandbox reason.
