Midnight Commander is very slow when starting and changing directories

Tried to list all drive letters (with help of

    PS C:\Users\chanibal> wmic logicaldisk get
    Caption  DriveType  ProviderName  VolumeName
    C:       3                        SSD
    D:      3                        HDD
    E:       5               <------------ this is a DVD drive not
used for months (years?)

And it took close to the 4 seconds - similar to the issue I am experiencing:

    PS C:\Users\chanibal> Measure-Command { wmic logicaldisk get
caption,providername,drivetype,volumename }
    TotalSeconds      : 5,0886857

Disabling the DVD drive with Device Manager changed the above time to
0.063s, changed `ls /cygdrive` time to 0.015s and Midnight Commander

All right, now the question is WHY did this fail - I think it might be
considered Cygwin bug material, almost none windows app has failed
this way (with the exception of this windows mc build).
