# Sticking an acquire/release pair around the 'import' statement makes the
# problem go away.

# I believe that what happens is:
-#
+#
# 1) The first thread to hit the import atomically reaches, and executes
# most of, get_module. In particular, it finds Lib/whrandom.pyc,
# installs its name in sys.modules, and executes
-#
+#
# v = eval_code(co, d, d, d, (object *)NULL);
-#
+#
# to initialize the module.
-#
+#
# 2) eval_code "ticker"-slices the 1st thread out, and gives another thread
# a chance. When this 2nd thread hits the same 'import', import_module
# finds 'whrandom' in sys.modules, so just proceeds.
-#
+#
# 3) But the 1st thread is still "in the middle" of executing whrandom.pyc.
# So the 2nd thread has a good chance of trying to look up 'randint'
# before the 1st thread has placed it in whrandom's dict.
-#
+#
# 4) The more threads there are, the more likely that at least one of them
# will do this before the 1st thread finishes the import work.
-#
+#
# If that's right, a perhaps not-too-bad workaround would be to introduce a
# static "you can't interrupt this thread" flag in ceval.c, check it before
# giving up interpreter_lock, and have IMPORT_NAME set it & restore (plain
# clearing would not work) it around its call to import_module. To its
# credit, there's something wonderfully perverse about fixing a race via an
# unprotected static <grin>.
