FWIW, Corinna has identified a possible culprit (different behavior of
NtQueryInformationFile under WinXP SP2).  Hopefully the author of the
recent pipe handling code changes will be able to fix this (maybe by an
SP2-specific workaround for the problem).  Until then, Karl will either
have to use the previous version of cygwin1.dll, or compile his own CVS
HEAD version with the corresponding pipe patch reverted.
