Running setup.exe from bash, or with strace, eliminates the problem. My
experience is that setup MUST be run from Explorer.

I've attached stripped down versions of Xfree-bin-icons.sh (and related
scripts).
I can reproduce it like this:
- Put "part1.sh" in /etc/postinstall
- put "part[23].sh" in /
- ...and run setup.exe from Explorer

Choose
- Leave virus scanner alone (I have F-secure)
- Install from local dir
- Select root install dir
   Root dir "C:\Program\cygwin"
   For All users
   Unix text file type
- LPD: G:\cygwin-downloads
<parses ini file>
<checks MD5 sums - EVERY TIME. Is this REALLY necessary?>
- Select packages

When the "part1.sh" script gets executed, it hangs... which can look like
this from bash (in rxvt):

This is with ONE extra bash+rxvt running while the test is done. No other
cygwin tasks exist at test time.

BTW: setup - "Create icon on Desktop" is not remembered, I was wrong before.
