Update of /cvsroot/python/python/dist/src/Misc
In directory sc8-pr-cvs1:/tmp/cvs-serv1904

Log Message:
Provide access to the import lock, fixing SF bug #580952.  This is
mostly from SF patch #683257, but I had to change unlock_import() to
return an error value to avoid fatal error.

Should this be backported?  The patch requested this, but it's a new
feature.

+ 
+ - The imp module now has ways to acquire and release the "import
+   lock": imp.acquire_lock() and imp.release_lock().  Note: this is a
+   reentrant lock, so releasing the lock only truly releases it when
+   this is the last release_lock() call.  You can check with
+   imp.lock_held().  (SF bug #580952 and patch #683257.)
  
  - Fix some bugs in the parser module.  SF bug #678518.
