Thank you for your reply.

OK, now closed.  If anyone else runs into any issues, they can always
open a new bug report.

Today I update my Gentoo:

	> emerge --update --newuse --deep @world

in Eshell.  After a very long output (40M+), the shell started stuttering and hanging, messaging the following errors on every new line of output:

	error in process filter: eshell-watch-for-password-prompt: Stack overflow in regexp matcher
	error in process filter: Stack overflow in regexp matcher

The process became so slow it was unlikely it would ever complete, so I terminated it and had to re-run it in a *term*.
