Steps to repro:

1. Open Unity 5.4.0p4;
2. Create new empty project;
3. Observe console.

Actual result:

'Threadsafe Linear allocator (Job temp alloc) has allocations that are more that 2 frames old - this is not allowed and likely a leak'

error is shown when starting/opening new project in Unity 5.3.2p4.

Regression introduced 5.3.2p4.

Expected result:
Allocator errors should not be shown after creating/opening new project.

Notes:
- Happens on Windows 10 (stably);
- On OSX happens when launching Unity only for the first time;
- Reproducible in: 5.3.2p4;
- Not reproducible in 5.3.2f1, 5.3.1f1, 5.4.0b7;
- Issue also reproduces when sculpting terrain (painting height) - in this case, allocator errors are constantly spawned.
