[issue4926] putenv() accepts names containing '=', return value of unsetenv() not checked

as putenv() can't set a name that unsetenv() can fail to remove. I did however find one more case where that can happen, which is with an environment variable that has an empty name. Linux at least allows such variables to be set and passed to new processes, but its unsetenv() will not remove them

. Perhaps, because putenv is supposedly not available on all platforms? Any way, I think the OP was asking to always get the value dynamically when ever os.environ['VAR'] or os.getenv['VAR'] is done.
