IOErrors after running a command

[ngo]

I've installed mona.py as per instructions, but had to build x64dbgpy from sources (because snapshot artifacts are not available, see x64dbg/x64dbgpy#35).
Now after every command with mona I get an IOError, e.g

import mona
mona.mona('modules')

===>

[+] Command used:
!mona modules

---------- Mona command started on 2019-07-19 09:04:28 (v2.0, rev 577) ----------

Not sure that it is relevant, but

• I've retargeted x64dbgpy build into VS2019 on Win10.
• I also used swig 4.0.0, which dropped the -ouputtuple (see -outputtuple is removed in swig 4.0.0. x64dbgpy#36), so I had to delete this option from swig/setup.py

[ngo]

Removing the line self.__original_stream.write(text) from hooks.py mitigates the issue, but I'm not sure what happens to the original file descriptor.
