If the ruby process is launched with its standard input closed, it does not behave very well.  The following output was logged by the ruby process under these circumstances.  The attached source file can be used to produce a minimal executable that duplicates the issue.  Note that this appears to be something that changed between 1.9.2 and 1.9.3.

[BUG] rb_update_max_fd: invalid fd (0) given.
ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux]
