threads branch: test failures on darwin/intel

Sorry to be the repeat bearer of bad news about the threads branch, but ...

In recent weeks I have had access to a Darwin/Intel box -- not my 
beloved and ancient Mac OS X 10.4 running Darwin/PPC.  When testing the 
threads branch on this box, I get failures in two files in which I have 
not previously (or, at least, recently) gotten failures.  The failures 
occur consistently in t/src/extend.t and intermittently (sigh) in 

I. t/src/extend.t:  Test 19 fails

#   Failed test 'multiple Parrot_interp_new/Parrot_x_exit cycles'
#   at t/src/extend.t line 727.
# Exited with error code: [SIGNAL 6]
# Received:
# Starting interp 1
# Destroying interp 1
# Starting interp 2
# Destroying interp 2
# Expected:
# Starting interp 1
# Destroying interp 1
# Starting interp 2
# Destroying interp 2
# Looks like you failed 1 test of 19.
t/src/extend.t ......... Dubious, test returned 1 (wstat 256, 0x100)

II. t/src/embed.t:

#   Failed test 'Minimal embed, create multiple interps without giving 
1st interp to Parrot_interp_new '
#   at t/src/embed.t line 113.
# Exited with error code: [SIGNAL 6]
# Received:
# Done
# Really done
# Expected:
# Done
# Really done
Looks like you failed 1 test of 13.
t/src/embed.t .......... Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/13 subtests
	(less 1 skipped subtest: 11 okay)
Between config/init/ and config/init/hints/, our 
default build settings for Darwin are (correct me if I'm wrong):

   --cc=gcc --link=g++ --ld=g++

As time would permit, I tried both these settings and "all-gcc" and 
"all-g++" builds.  t/src/extend.t failed all three ways.  t/src/embed.t 
did *not* fail all three ways, but unfortunately I didn't have time to 
note down all the combinations.

I know that there are other contributors who work on Darwin/Intel, so 
perhaps we can get more data.

Thank you very much.
