No, this is not mintty's fault.  You have to understand that the
request for information from the DC is called before the actual
application had any chance to initialize,  This happens before
the application has, in fact, been called from the Cygwin DLL.

Therefore, if the three seconds are a burden, there are three choices
going forward:

- We reduce the timeout to 1 second in general, which could be a problem
  when utilizing a slow VPN conncetion to the DC,

- We allow the user to specify a timeout value and set the default to
  1 second.

- We stick to the 3 seconds and users should switch to files (/etc/passwd
  /etc/group) when being offline from their DC.

I'm really not sure what the best way is, I guess we as a community have
to dice this out somehow.
