Description

Even if nothing changes or after any minor change that shouldn't require reparsing all the TUs.

The visible TUs are restarted immediately and the non-visible TUs are killed and restarted the next time they're made active.

It seems like it should only reset things if there's an actual configuration change.

Seem to be caused by

cpptools/didChangeCustomBrowseConfiguration
cpptools/clearCustomConfigurations

Maybe we can just check if the browse configuration is identical and skip the processing.

Research direction

Start by tracing the cpptools/didChangeCustomBrowseConfiguration and cpptools/clearCustomConfigurations entry points mentioned in the issue. Compare the browse configuration before processing and verify that identical configurations do not restart visible or later-activated translation units, while actual configuration changes still trigger the reset.
