maybe the dispatcher may not need to be set each time as well?

This PR was submitted for the master branch but it was merged into the 2.2 branch instead (closes #8242).

This works well apart from unnecessarily reloading the command classes from all included bundles each time doRun() is called (https://github.com/symfony/symfony/blob/master/src/Symfony/Bundle/FrameworkBundle/Console/Application.php#L68). This can also lead to running out of file descriptors under heavy load as bootstrap.php.cache uses a RecursiveDirectoryIterator to load the command.

This PR was merged into the master branch. Discussion ---------- [FrameworkBundle] fixed regression where the command might have the wrong container if the application is reused several times | Q | A | ------------- | --- | Bug fix? | yes | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | n/a | License | MIT | Doc PR | n/a This fixes a regression introduced in #8242. Before this PR, the commands were always getting the current container registered in the kernel. But as the commands are now registered only once, if the container changes, the commands were not aware of this change. That happens quite frequently in functional tests where the Kernel is booted and shutdown several times in the same process.

I have been experimenting with using the Symfony console application inside of a React event loop which works quite well.
In this scenario, I re-use an instances of a Console\Application to run multiple tasks. This works well apart from unnecessarily reloading the command classes from all included bundles each time doRun() is called (https://github.com/symfony/symfony/blob/master/src/Symfony/Bundle/FrameworkBundle/Console/Application.php#L68). This can also lead to running out of file descriptors under heavy load as bootstrap.php.cache uses a RecursiveDirectoryIterator to load the command.
