This PR fixed performance problem in dev mode and prevent logs serialize several times for each sub-request.
STR:
1) Install any symfony application v2.8-3.4
2) Create a simple page with 20-50 sub-requests and 5k-10k logs
3) Open page in dev mode
**Actual**
- debug toolbar not open (404 not found)
- sets of logs (in the logger debug panel) for different requests are same
- log processing takes about 20-30s
- gc also run about 50% of execution time
**Expected**
- Debug toolbar should be open
- As developer, I want to see in logger panel only those logs that are relevant to the given sub-request
### Profile and performance
Tested on page with 7k logs and 70 sub-request.
