I already wanted to file a bug because of unexpected behaviour I was dealing with for the last DAY
but as it turns out it just NOT documented behaviour

BrowserKit docs tells nothing about KernelBrowser::disableReboot() method

I was thinking a lot why all of my mocks just disappeared and test started using real services, real http_clients...

All the container was rebooted after the first request because of the default behaviour that HAS NOT BEEN DOCUMENTED YET

I'm crying
