I have seen similar issues on Ubuntu.  I believe it may be related to 
the complicated way the line number field is kept in sync.

The only workaround I've tested is writing my own script editor, 
thankfully subsidized by a generous soul who commissioned it.  It's not 
yet ready for prime time, though, so I have no immediate solution for LC 
SE users.

There should not be, at least within reasonable memory limits.

And if there were, it shouldn't be anywhere near as short as 5900 lines. 
I've been stress-testing my with 20k-line scripts.

The LC field object is quite good.  Any script editor using it should be 
quite good too.
