Script command under NetBSD-current

[Dave Tyson <dtyson%anduin.org.uk@localhost>]

I thought I noticed an issue with the script command under NetBSD-current a 
few weeks ago, but recently stumbled on it again.

This is under:

NetBSD cruncher2.anduin.org.uk 9.99.83 NetBSD 9.99.83 (GENERIC) #2: Tue Jun  8 
19:42:49 GMT 2021  
root%cruncher2.anduin.org.uk@localhost:/usr/obj/sys/arch/amd64/compile/GENERIC amd64

If you issue a script command, run a process with takes a little while and 
then an exit command to close the script file and return to a command prompt. 
viz: 

cd /usr/pkgsrc
script /tmp/ll
cvs update -dP
exit

what happens is you don't get a command prompt - its like the script command 
freezes and doesn't return. Issuing a ps shows the script processes:

USER     PID %CPU %MEM   VSZ   RSS TTY   STAT STARTED    TIME COMMAND  UID  
PID PPID  CPU PRI NI   VSZ   RSS WCHAN   STAT TTY      TIME COMMAND
root    1250  0.0  0.0 17812  1516 pts/0 I+    5:40PM 0:00.00 script     0 
1250 1115    0  85  0 17812  1516 ttyraw  I+   pts/0 0:00.00 script /tmp/ll 
root    1252  0.0  0.0 17924  1304 pts/0 I+    5:40PM 0:00.32 script     0 
1252 1250    0  43  0 17924  1304 parked  I+   pts/0 0:00.32 script /tmp/ll 

Both appear to be idle. Killing the parent process returns a command prompt.

Anyone else seeing this?
