Bug ID: 35344
           Summary: Cygwin's post-install scripts fail on fork errors
           Product: Wine
           Version: 1.7.5
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
    Classification: Unclassified

Executing 'wine setup-x86.exe' seems to work quite well (you can step through
the wizard, packages are downloaded and extracted) until the post-installation
bash scripts are executed.

Then I get for each script a message like:

running: C:\cygwin\bin\bash.exe --norc --noprofile
"/etc/postinstall/glib2.0.sh"

/etc/postinstall/glib2.0.sh: fork: retry: Resource temporarily unavailable
/etc/postinstall/glib2.0.sh: fork: Resource temporarily unavailable

abnormal exit: exit code=254

The fork error message are always displayed after some kind of timeout.

Where to get the setup-x86.exe:

http://cygwin.com/setup-x86.exe

$ md5sum setup-x86.exe
c9818d3500e42fd9eb755d424450871a  setup-x86.exe

Executing Cygwin's setup exe inside wine looks a little bit silly, but I want
to create a reference cygwin installation for deployment purposes.
