Introduce a synchronization mechanism between attach-f-p and strace. * tests/attach-f-p-cmd.c: New file. * tests/Makefile.am (check_PROGRAMS): Add attach-f-p-cmd. * tests/attach-f-p.c: Include <sys/stat.h>. (main): Write to stdout instead of descriptor 3. Wait for the peer writing to stdout. * tests/attach-f-p.test: Assume that ./attach-f-p-cmd works. Use $OUT for expected output. Use attach-f-p-cmd for unlocking $OUT.
