Can you elaborate?  Cygwin supports multiple installations just fine 
these days.  Use of a .bat file (an intervening cmd.exe process) should 
isolate the environments for this test.

Regardless, I was also able to produce a hang in bash running the same 
.bat file from a cmd.exe prompt using only the snapshot install and the 
copied bash.exe, false.exe, and dependent binaries - no mintty.  The 
hung bash.exe process eventually timed out with an error message:

5 [unknown (0x176C)] bash 2000 sig_send: wait for sig_complete event 
failed, signal 6, rc 258, Win32 error 0
