New Revision: 61665

Modified:
   python/trunk/Lib/test/test_fcntl.py
   python/trunk/Lib/test/test_ioctl.py
Log:
Attempt to fix the Solaris Sparc 10 buildbot.  It was failing with an invalid
argument error on ioctl.  This was caused by the added test_fcntl ioctl test
that hard coded 0 as the fd to use.  Without a terminal, this fails on solaris.
(it passed from the command line on sol 10, both 32 and 64 bit)

Also, test_ioctl exists so I moved the test into there where it belongs.
