New Comment:
I think I tracked down the leak.
In this function:
TSRM_API void *ts_resource_ex(ts_rsrc_id id, THREAD_T *th_id)
There's at the end this:
TSRM_SAFE_RETURN_RSRC(thread_resources->storage, id,
thread_resources->count);
Now if I uncomment this. It does not leak the memory for the 2 calls
from my last post.
The call translates to
return &thread_resources->storage;
Why should this leak? Please, C++ people help us here.

I have been digging more into this issue and I have found this.
1. HttpExtensionProc like this does not leak at all.
DWORD WINAPI HttpExtensionProc(LPEXTENSION_CONTROL_BLOCK lpECB)
{ return 0; }
2. 1. HttpExtensionProc like this does leak.
DWORD WINAPI HttpExtensionProc(LPEXTENSION_CONTROL_BLOCK lpECB)
{
TSRMLS_FETCH();
ts_free_thread();
return 0;
}
It is clear that the ts_free_thread does not free everything. I'm not a
C/C++ guru please people help here. This issue has been here since 2
years ago and nobody fixed it yet. Let me know.

I can send you a small tool I made. It connects to any web server and
issues the GET /... HTTP command in a given cycle and given number of
threads. You can test it easily with it. It's very handy. Just let me
know.

That's what I thought of too so I removed all extensions and the
results I posted are without any extensions.

You have some extensions loaded in php.ini, right?
Which ones are those? What if you don't load them?

The problem is still there. Nothing has changed.
I performed the same 2 tests.
1. LoadLibrary and FreeLibrary - 200 cycles = 50MB leak
2. HttpExtensionProc - 1000 calls = 500kB leak
Please, let me know how can I help.
