[jira] [Commented] (MINIFICPP-1065) Review UUID implementation thread safety

    [ https://issues.apache.org/jira/browse/MINIFICPP-1065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16970218#comment-16970218 ] 

Dániel Bakai commented on MINIFICPP-1065:
-----------------------------------------

The UUID implementation is not thread safe on any platforms, and the time-based implementation has a large number of collisions if multiple threads are generating UUIDs.

> The time-based windows version does not seem thread-safe.
> Also, adding an uuid implementation using the native UuidCreateSequential might be better.
