There are cases where a user:A commits and wants to get the commit meta immediately after the operation.
However under race conditions another user:B commits as well before user:A acquires the meta data.
Thus by the time user:A executes $commitId = $repo->getLastCommitId() the last commit pointer is moved and user:A receives the commitId of user:B commit.

Please, if possible, provide any of these methods. Any of them would work:

$commitsBack = 10; // if commits number is smaller than 10 get all available
$commitIdsArray = $repo->getLatestCommitIds($commitsBack); // returns array of commit_ids 
// or
$commitsArray = $repo->getLatestCommits($commitsBack); // returns array of Commit:class instances 

Thank you in advance
