Linux’s implementation of open() on FIFOs suffers from a race condition (see http://marc.info/?l=linux-kernel&m=134071285509470 ) that causes t9010-svn-fe.sh to occasionally fail with t9010-svn-fe.sh: 27: eval: cannot create backflow: Interrupted system call Although I can’t reproduce this locally, it happens particularly often on the Launchpad PPA builders. Sidestep this problem by opening the backflow FIFO once for read+write. Also, replace the stream FIFO with a shell pipe so we don’t have to do manual process management.
