If pid is not a children of os.getpid() (current process) just waits until the process disappears and return None. If pid does not exist at all return None immediately.

Return disk usage associated with path. Note: UNIX usually reserves 5% disk space which is not accessible by user. In this function "total" and "used" values reflect the total and used disk space whereas "free" and "percent" represent the "free" and "used percent" user disk space. r )Z_round)�total�usedZfreeZpercent)r r �statvfs�UnicodeEncodeError� isinstancer �encode�sys�getfilesystemencoding�f_blocks�f_frsize�f_bfree�f_bavailr r )�path�str( Z avail_to_rootZ avail_to_userr) Z total_userZusage_percent_userr r r r w s( c C sp i } t j d�t j d� }xR|D ]J}y|| tj|�j< W q tk rf } z|jtjkrV� W Y dd}~X q X q W | S )zMGet a map of device-id -> path as a dict.
