summary:
  Ignore IOException if attempting to truncate file for write

Opening files for write will call FileChannel#truncate(0). For special
files like /dev/null, such calls raise IOException, which is not
specific. Attempting to distinguish with the exception message causes
internationalization issues (http://bugs.jython.org/issue1944), so
simply suppress. This should just work, since other more detailed
exceptions are raised for cases like attempting to write to say
/dev/cannot-write-here
