Concurrent extraction of convenience-library components on OS X

[Akim Demaille]

Hi all,

I'm having the following problem with the current Libtool from master,  
see the attached log.

I have two dlopen-modules that use a common convenience library.  If  
I'm unlucky, libtool will try to extract the objects from the  
convenience library at the same moment, which ar does not seem to like.

libtool: link: (cd runner/.libs/runner.lax/libconfig.a && ar x "/Users/ 
akim/src/gnet/_build/i386-apple-darwin9.6.0/lib/config/.libs/ 
libconfig.a")
libtool: link: (cd muxer/.libs/muxer.lax/libconfig.a && ar x "/Users/ 
akim/src/gnet/_build/i386-apple-darwin9.6.0/lib/config/.libs/ 
libconfig.a")
ar: /Users/akim/src/gnet/_build/i386-apple-darwin9.6.0/lib/ 
config/.libs/libconfig.a: Resource temporarily unavailable

Indeed, running several "ar x /tmp/foo.a" concurrently from different  
directories fails on OS X.

Cheers,

        Akim
