+Subject: [PATCH] Fix iohelper usage with streams opened for read
+
+In b2878ed860ceceec3cd6481424fed0b543b687cd we added the O_NOCTTY
+flag when opening files in the stream code. Unfortunately a later
+piece of code was comparing the flags == O_RDONLY, without masking
+out the non-access mode flags. This broke the iohelper when used
+with streams for read, since it caused us to attach the stream
+output pipe to the stream input FD instead of output FD :-(
