[omniORB] consecutive sequences?

[Alexy Khrabrov]

An efficient way to fetch rows from a database is by using a bulk
load into array, when all the rows are loaded into the array at once.
The array, of course, must be a solid consecutive chunk of memory.
Does omniORB implement the sequence type so that it's consecutive?
In the examples I saw, a sequence is gradually enlarged with length(),
and each new element is allocated on the heap, which is clearly 
not array-like...
