    It's not a priority issue. It's correctly set to run at "Fixed Class" 
    priority. 
    
    Are you on UnixWare 2.1.3?
    
    I just upgraded to 2.1.3 and now my faxgetty takes 50% of the available
    CPU time as reported by "ps -A -ouser,pid,ppid,pcpu,vsz,time,tty,args".
    
    Truss(1) shows pages of
    read(1, 0x080473DC, 2047)                       = 0
    poll(0x08045BC4, 2, -1)                         = 1
    read(1, 0x080473DC, 2047)                       = 0
    poll(0x08045BC4, 2, -1)                         = 1
    read(1, 0x080473DC, 2047)                       = 0
    poll(0x08045BC4, 2, -1)                         = 1

looks like the common CONFIG_OPENFIFO problem (but never saw this
in faxgetty(1M) before); what is fd 1 for a file?

    With faxgetty running rtpm(1M) shows 
          CPU:
        100 %u+s
          0 %w+i
         54 %usr
         46 %sys
          0 %wio
          0 %idl
    
    With no faxgetty.
          CPU:
          1 %u+s
         99 %w+i
          1 %usr
          0 %sys
          0 %wio
         99 %idl
    
    I hate it when OS upgrades break things. It worked good on 2.1.2
    I'm going to recompile HylaFAX from scratch to see if that makes any
    difference.
