$ mv myPostinstall.sh.done myPostinstall.sh
$ rm /postinstall.strace
$ strace -o /postinstall.strace  /install/setup.exe

 Hrm... The hang doesn't occur.

Checking:
$ mv /postinstall.strace /postinstall.strace-nohang
$ mv myPostinstall.sh.done myPostinstall.sh
$ /install/setup.exe

 No hang. 8-I

Tried strace on postinstall/Xfree-bin-icons.sh - which have been doing the
hang.
-> No hang.


Thinking about file/dir rights settings: With PI/Xfree...sh in mind;

Testing this one again...

It hangs. cygpath and one instance of bash is left behind if one hits
cancel. Killing cygpath makes them disappear.

Any ideas?
