iPyEvalInt("os.getpid()") cause MT4 hang about otmql4py

[mich000r]

I'm facing the same issue. After execution of OTPyTestNullEA.mq4 my log shows:

del _active[_get_ident()]
KeyError: 5584

After enhancing exception handling in threading.py it seems to me that the _get_ident() returns the wrong ThreadId. The MainThread id is 4876. The function at this point returns 5584. Refer to stackoverflow this issue could be triggered by monkey pathing.
