Creating deep services fails

[viters]

From docs:

Any depth of injection is supported (ServiceA can depend on ServiceB which depends on ServiceC and so on). A service can also depend on as many services as it would like (ServiceA can depend on service D, E and F etc). Howerver, services cannot have circular dependencies.

Creating larger than 7-depth services fails: https://go.dev/play/p/QwAmt1aIbiE

panic: 1. write lock is not held by this thread
2. an error occurred while getting the dependencies of default#Component3.1.5
3. an error occurred while getting the dependencies of default#Component4.1.6
4. an error occurred while getting the dependencies of default#Component5.1.7
5. an error occurred while getting the dependencies of default#Component6.1.8
6. an error occurred while getting the dependencies of default#Component7.1.9
7. an error occurred while getting the dependencies of default#Component8.1.10

In real-project we also experienced IOC error: function called from non-goethe thread and sometimes code just hangs on goethe lock acquire in gotethe cache/cache.go:243.

Workaround

If the depth of creation is smaller (ex. something existed previously), it works: https://go.dev/play/p/SVmmLqr3_6I

The problem seems to be caused by GetThreadID in goethe_factory.

When creating services 8 to 2, TID is correctly calculated as 22. There are two xXTidFrame in stacktrace:

On next recursion, when creating service 1, TID is calculated as 6, there is only one xXTidFrame in stacktrace:

I thought that maybe debug.Stack() is not returning everything but it does seem to. Maybe the recursive lock is not ready to handle 8 write recursions?
