No, it made no difference.

In fact it was the kernel compilation. I had used the light
ramfs version of tmpfs. However apparently python requires the full
shmem version... It bails out at this point of the strace:

statfs("/run/shm", {f_type=0x858458f6, f_bsize=4096, f_blocks=0, f_bfree=0, f_ba
vail=0, f_files=0, f_ffree=0, f_fsid={0, 0}, f_namelen=255, f_frsize=4096}) = 0
read(12, "", 1024)                      = 0
close(12)                               = 0
munmap(0x33c24e61000, 4096)             = 0
futex(0x33c325d6330, FUTEX_WAKE_PRIVATE, 2147483647) = 0
write(2, "Traceback (most recent call last"..., 35Traceback (most recent call la

The kernel did have /run/shm and /run mounted as tmpfs, and did have
futex but it's not enough.

Sorry about the noise. I'll close the bug.
