Test hang on _SynDBRemote caused by THttpApiServer.Destroy

Hi,

The new changes related to (fClones: THttpApiServers) resulted the test process hang at THttpApiServer.Destroy (...finally inherited Destroy ...).
When I restored the code back to the version (fClones: TObjectList), the test passed as usual.
Any help would be appreciated.

I was wondering when this problem (which I did see sometimes) come from.
I will check the fClones commit, i.e. https://synopse.info/fossil/info/10b0598e32315138

I guess, this could relate to https://synopse.info/forum/viewtopic.php?id=5327 as well?

Yes, this is the same code.

What it weird is that it should happen with the previous code too, but less often due to some weird multi-thread magic.

Should be fixed by https://synopse.info/fossil/info/f640a7dc402c311c

The fix was not enough.
Please try https://synopse.info/fossil/info/b2c2d46be6 - which seems fine now in my tests.

The problem was when you had no cloned thread, i.e. ThreadPoolCount=1.
