Well I wouldn't worry.  Generally the file size limit is governed by
the process' "ulimit".  On the UNIX pc it's set to: 2147483647, yes
the size of a "signed long".   And that's in blocks :-)

We have B-tree data and index files well over 25 megs on some UNIX PC
systems for our application!  Now if there was only a way to increase
the block size to something like 2048, instead of 512.  That would
certainly increase performance slightly!
