Usually after installation of a new snapshot i begin with a compilation
of the sources. Today the compilation fails in winsup/cygwin/mkimport
(perl script) with the following messages:
      1 [main] perl 2380 child_info_fork::abort: unable to map Glob.dll, Win32 error 126
      4 [main] perl 5460 child_info_fork::abort: unable to map Cwd.dll, Win32 error 126
      5 [main] perl 5916 child_info_fork::abort: unable to map Glob.dll, Win32 error 126
      4 [main] perl 4028 child_info_fork::abort: unable to map Cwd.dll, Win32 error 126
      4 [main] perl 4900 child_info_fork::abort: unable to map Glob.dll, Win32 error 126
      4 [main] perl 2128 child_info_fork::abort: unable to map Cwd.dll, Win32 error 126
      4 [main] perl 5120 child_info_fork::abort: unable to map Glob.dll, Win32 error 126
      4 [main] perl 5440 child_info_fork::abort: unable to map Cwd.dll, Win32 error 126
      4 [main] perl 5044 child_info_fork::abort: unable to map Glob.dll, Win32 error 126
      4 [main] perl 5456 child_info_fork::abort: unable to map Cwd.dll, Win32 error 126
etc.

at the pace one message each 5seconds.
All processes indicated remain in /proc, as <defunct>, and with
maps "permission denied".
