Minor updates for BeOS R5. Use of OSError in test.test_fork1 changed to TestSkipped, with corresponding change in BeOS/README (by Fred). This closes SourceForge patch #100978.

+   If test_popen2 does hang, you can find the semaphore it's hung on via the

+./python -tt ../src/Lib/test/regrtest.py (team 26922) (uid 0) (gid 0)
+  39472               python  sem  10    3785    1500 piperd(360526)

+   That last number is the semaphore the fork()'d python is stuck on
+   (see how it's helpfully called "python lock (1)"? :-).  You can unblock
+   that semaphore to let the tests continue using the "release" command
+   with that semaphore number.  Be _very_ careful with "release" though,
+   releasing the wrong semaphore can be hazardous.

    Expect the following errors:
 
-   test_grp crashed -- exceptions.KeyError : getgrnam(): name not found
-   test_pwd failed -- Writing: 'fakename', expected: 'caught e'
-   test_socket crashed -- exceptions.AttributeError : SOCK_RAW
+   test * skipped -- an optional feature could not be imported (you'll see
+                     quite a few of these, based on what optional modules
+                     you've included)
+
+   test test_fork1 skipped -- can't mix os.fork with  threads on BeOS
+
+   test test_re failed -- Writing: '=== Failed incorrectly', expected: 
+                          "('abc', 'abc', 0, 'fou"
+
+   test test_select crashed -- select.error : (-2147459072, 'Bad file 
+                               descriptor')
+
+   test test_socket crashed -- exceptions.AttributeError : SOCK_RAW
 
    These are all due to either partial support for certain things (like
    sockets), or valid differences between systems.
 
-   NOTE: On R4/x86, the pause() function is broken; expect the signal
-         module test to crash Python!
+   That test_re failure is a little worrysome though.
 
 7) Install:
 
    make install
 
 8) Enjoy!
