[vile] vile eating CPU and then dumping core after pkill

[Gary Jennejohn]

OK, this may be unreasonable, but here's my story.

BTW FreeBSD 9-current.

I was editing a file with vile, which per wc -l has 132,096 lines.

I moved part way through the file and entered dG; vile would have had
to delete about 110,000 lines.

It may be unreasonable and I don't know the inner workings of vile, but it
seems like dG should just do something like "hey, I know where I am and
I know where the end of the buffer is, so I'll just pretend that the
buffer ends here now" rather than noodling around for a long time with
no apparent effect, other than printing ...working in the status line.

After waiting about 10 minutes, during which vile was eating 100% of one
of my two CPU cores, I got tired of it and pkill'd it.

vile dumped a core (may be a bug in the threading code).

Here's the output from gdb FWIW:
