When using Merge Before Build, sometimes throws error:
git merge --ff df24f37fedf6048881cc0683a782c975b0bd8db7 # timeout=10
ERROR: Timeout after 10 minutes
> git config core.sparsecheckout # timeout=10
> git checkout -f df24f37fedf6048881cc0683a782c975b0bd8db7 # timeout=20
FATAL: Could not lock repository. Please try again

and next build in the same workspace is failed with error:
FATAL: Could not lock repository. Please try again

This happens because my repositore is very big. I want set a merge timeout or kill git process before next try.
Thanks
