I'm unaware of any loose ends, could you clarify?
Btw. $gmane/237814 seems to be a different topic, the version in next (and now
in pu) was $gmane/237429.

Damn, a day too late :-) I found these two glitches today...is a fixup patch OK
or should I do a reroll (or separate patch on top)?
Thanks,

Subject: [PATCH] fixup! add a hashtable implementation that supports O(1)
removal
Use 'unsigned int' for hash-codes everywhere.
Extending 'struct hashmap_entry' with an int-sized member shouldn't waste
memory on 64-bit systems. This is already documented in api-hashmap.txt,
but needs '__attribute__((__packed__))' to work. Reduces e.g.
struct name_entry {
struct hashmap_entry ent;
int namelen;
char *name;
};
from 32 to 24 bytes.
