Yeah.  My opinion is that we should just qsort the list of targets

In the meantime, would you mind cleaning this up:

nbtxlog.c: In function 'btree_xlog_split':
nbtxlog.c:269: warning: 'newitem' may be used uninitialized in this function
nbtxlog.c:269: note: 'newitem' was declared here
nbtxlog.c:271: warning: 'newitemsz' may be used uninitialized in this function
