port math/gnuplot hangs and ignores "kill -9"

[Anton Shterenlikht]

on ia64 HEAD,  gnuplot-4.2.6, any plot command
hangs the program. top shows gnuplot is using 100% of CPU,
yeat CPU time is zero:

  PID    UID    THR PRI NICE   SIZE    RES STATE   C   TIME   WCPU COMMAND
60071   1001      2  48    0 98008K 51424K CPU1    1   0:00 100.00% gnuplot

kill -9 60071, either from my account, or from root,
has no effect, the process is still there.

I cannot find a way to terminate this hanged process without reboot.

This seems to be a regression.

Please advise

many thanks
