here is simple shell script attached.
i'm using 32-bit windows. and the attached doesn't invoke timeout of 
cygwin land.
. execute following line in non-cygwin process.(typically in cmd.exe)
sh ./test
. ctrl+c before *press any key to continue* disappear, and you are *jammed*
. whenever you ctrl+c while process hang, ctrlc handler thread would 
continue to be attached to child sh process.
