It doesn't hang for me, but it is significantly slower.  I'm running
the latest development release.  Tasklist appears to be WMI heavy.  I
ran Process Monitor and it appears that when running tasklist /m under
bash, WMI is significantly more active.  WMI actually opens tzres.dll
(Time Zone Resources) about 150,000 times vice a mere 800 times when
executing through a standard command prompt.  Moreover, WMI really
doesn't appear to be doing much of anything with tzres.dll... just
open/close/open/close/open/close.  Very curious indeed.
