osrm-datastore on macOS and win do not wait for clients to switch #7320
Description
Issue
osrm-datastore on macOS and Windows does not wait for other processes to detach from shared
memory before exiting. Instead it sleeps for 50ms and then boldly announces: 'All clients switched.'
Symptoms:
- Cucumber tests fail randomly because queries are executed against old data when 50ms were not enough for clients to switch
- Cucumber tests do not run as fast as they could run when 50ms is plenty to switch
Steps to reproduce
This happens with the new Parallel Cucumbers PR #7309
Specifications
