 It often is :-)

 I'm running a fairly recent version of -current but it still happens.

 Since I use Java, the memory limits are set higher and the box only has 512M.
 If you have more memory, it might not feel so bad to you.
 
 $ ulimit -a

 The machine is unusable while it frees pages for the 'more' process.
 'more' doesn't respond, not even after paging has stopped.
 I normally have LESS='-e' in my environment but removing it makes no difference.
 
 If you want more info, or for me to try something, just let me know.
