Re: Results using ULE

I switched back and forth between 4BSD and ULE several times on my P4 
system. The reason for this is that sometimes I would have rather long 
lapses in response (~30s) on the command line, especially when logged in 
on more than one terminal. On a recent occasion I was downloading 
sources with portupgrade's fetch only option and attempted to execute 
df. After typing in df and hitting return I got a new line but no output 
for a good 15-20s. Additionally during these periods I'm not able to 
switch terminals but hitting the enter key produces new lines.
