+//	to get their handle from their fileno and internally raise an "OSError":
+//
+//	[WinError 6] The handle is invalid"...
+//
+// Same error occurs when trying to retrieve a python file object from their descriptor
+//	using PyFile_FromFd. This is kinda weird since GetStdHandle is returning valid handles for them
+//	but oh well... reconnecting them seems to fix the issues from my testings.
