Unfortunately, this code is littered with different types for size and 
offset.  "int" is the most common but there are also off_t, size_t and 
some unsigned long as well.  Currently all of them are at least 32 bits 
so until we need to have an index larger than 32 bits, we should be OK. 
I agree, fixing them all is outside the scope of this patch.

The function as written can load any arbitrary subset of cache entries 
as long as previous_ce is set correctly.  I currently only use it on 
block boundaries but I don't see any good reason to limit its 
capabilities by moving what code passes the NULL in one function deeper.

Meh. Either way you have to figure out there are a block of entries and 
each thread is going to process some subset of those entries.  You can 
do the base + offset math here or down in the calling function but it 
has to happen (and be understood) either way.

I'll rename ieot_offset to ieot_start and ieot_work to ieot_blocks which 
should hopefully help make it more obvious what they do.

Thanks, good catch - I hate leaky code.

I understand the desire to get that part of the thread initialization 
out of the main line of this function (it's a bit messy between the 
entry counting and version differences) but I prefer to have all the 
thread initialization completed before creating the thread.  That allows 
for simpler error handling and helps minimize the state you have to pass 
into the thread (mmap_size in this case).
