multiple hg.exe processes spawned

[raleighr3]

When in a directory that is a mercurial repo multiple hg.exe processes are started and never die.
Basically one hg.exe for each time the enter key is pressed

λ tasklist /FI "IMAGENAME eq hg.exe"

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
hg.exe                        5028 Console                    1     25,928 K
hg.exe                        9756 Console                    1     25,912 K

hg.exe                       20340 Console                    1     25,860 K
hg.exe                       10948 Console                    1     25,928 K

hg.exe                       17372 Console                    1     25,924 K
hg.exe                       18380 Console                    1     25,924 K
hg.exe                        1340 Console                    1     25,924 K
hg.exe                       21764 Console                    1     25,924 K

To reproduce all I have to do is

1. start Cmder
2. change dir to a mercurial repo
3. press enter several times

Updated to 1.3.0 and still an issue, possible a bug in the lua runtime and/or parsing the output of hg.exe

modified clink.lua to the following and it resolved the issue

function get_hg_status()
    for line in io.popen("hg status -0"):lines() do
       return false
    end
    return true
end
