1. getrusage (platform/redox/mod.rs): Was returning all-zero rusage.
Now reads /scheme/proc/<pid>/stat from the kernel proc scheme and
fills ru_utime/ru_stime/ru_maxrss from real CPU time and RSS data.
RUSAGE_CHILDREN returns zeros (kernel doesn't track children's
resource usage yet — documented). Invalid who returns EINVAL.
2. pthread_key_create (pthread/tls.rs): Had a TODO for PTHREAD_KEYS_MAX
enforcement. Now checks keys.len() >= PTHREAD_KEYS_MAX (128) and
returns EAGAIN when the limit is reached. pthread_key_delete
automatically frees the slot.
3. pthread_condattr_setclock (pthread/cond.rs): Had a TODO for clock_id
validation. Now validates clock_id against CLOCK_REALTIME |
CLOCK_MONOTONIC (matching glibc behavior) and returns EINVAL for
any other clock. Removed the false 'Always successful' doc.
4. TCSETS/TCSETSW/TCSETSF (sys_ioctl/redox/mod.rs): Were all identical
(single combined match arm). Now three distinct branches: TCSETS
sets immediately; TCSETSW flushes output (TCOFLUSH) then sets;
TCSETSF flushes both queues (TCIOFLUSH) then sets. Flush is
best-effort via scheme 'flush' dup name (forward-compatible with
ptyd adding flush support).
5. dlfcn/mod.rs: Removed FIXME refactor comment in dlsym. All three
functions (dlopen/dlsym/dlclose) are real implementations using
the linker — the FIXME was only a refactor suggestion.
