1. Remove a unneeded field, bytes_avail, from orte_buffer_t. It is a calcualed value, and updating it everywhere is worse then just calculating it in the one place it is acutally used. 2. Change it so the default size of a orte_buffer is 128 bytes instead of 1024 bytes. We then double the size of the buffer up to 1024 bytes, then we additively increase the size by 1024 bytes at a time as was done before. This commit was SVN r14252.
