It wants to be big, because once it fills up, you have to disable gc. I have seen the table get as large as a quarter segment. Current algorithms prevent it from being larger than one segment, but it would be easy to make it 2 segments long. ** GC Overflow table is actually just a few words. Current microcode relies on it being in the same segment as GC Hash, but this is not very important. *** Pname char space is currently far too large for 32K litatoms; it might be about right for 64K, but we plan to dispose of it when pnames are hunked (taken as allocblocks), leaving just enough to get thru MAKEINIT. **** Want to allow a little extra space for DTD in case we expand number of datatypes. t h  t  hP TIMESROMAN TIMESROMAN  TIMESROMAN  TIMESROMAN C $ %) ' %2&1(+   3#!NVqz
