I had a thought regarding why it might be failing on the 252nd file,
which seems to be only touched but not written to. If my limit is set
somewhere in the Solaris O/S to 256 files then could SWISH-E have open:
251 temp files (swtmploc*)
2 index files (.index and .prop)
That just seems overly convenient that it matches up to 256 and then
dies, but I don't know if I'm overlooking something. Are there any open
file limits in Solaris 8 that default to 256? I thought that 1024 was
the default, but if something is 256 that might be the bottleneck in
