The file .hg/thgstatus contains one line for each directory that has removed, modified or added files (in that order of preference). Each line consists of one char for the status of the directory (r, m or a), followed by the relative path of the directory in the repo. If the file .hg/thgstatus is empty, then the repo's working directory is clean. Specify wait=True to wait until the system clock ticks to the next second before accessing Mercurial's dirstate. This is useful when Mercurial's .hg/dirstate contains unset entries (in output of "hg debugstate"). unset entries happen if .hg/dirstate was updated within the same second as Mercurial updated the respective file in the working tree. This happens with a high probability for example when cloning a repo. The overlay shell extension will display unset dirstate entries as (potentially false) modified. Specifying wait=True ensures that there are no unset entries left in .hg/dirstate when this function exits.
