+Summary: [PPC, IO-LAYER-NO-DAEMON] io-layer-no-daemon shows PPC -O2 deadlock with mcs
 I checked out Dicks new io-layer-no-deamon branch; and replaced the mono/io-layer directory 
 with it; upon installing the new io-layer mcs on OSX can never compile it just hangs.
 (it locks in CreateFile)

+kangaroo: that backtrace looks bogus - the symbol
+_wapi_handle_get_private_segment does not appear in the code any more,
+and I'd be very surprised if the abcremoval code started making socket
+You'll be pleased to know however that I've reproduced the deadlock. 
+It happens if the runtime is built with optimisation enabled (-O2
+here, I tend to build with CFLAGS set to just -g.)  This is a bug that
+Paolo was looking at a couple of weeks ago, but I don't know if he got
+to the bottom of it.
