-    toc_bytes = offsetof(shm_toc, toc_entry) +nentry * sizeof(shm_toc_entry)
+    toc_bytes = offsetof(shm_toc, toc_entry) + nentry * sizeof(shm_toc_entry)        + allocated_bytes;
I don't recall the exact reason, but this is intentional style
(memories from a patchwork with Tom). See for example geo_ops.c or
pl_funcs.c. Though it is true that things are not completely
consistent in the code with offset.

-    seg = dsm_create(shm_toc_estimate(&e), 0);
+    seg = dsm_create(segsize, 0);
Yep.

-    proc_exit(1);
+    proc_exit(0);
Agreed here. I don't see why this should not exit with 0 if there have
not been any errors.
