... Also we sort of have a problem since OPEN_MAX is not a constant on Linux x86. I guess that means a libc enforced behaviour or something for that bit
OPEN_MAX is described in the <limits.h> POSIX man page as a runtime invariant constant. However, it is allowed to be indeterminate, so no problems arise, I think.
