Hi Noah,

Until today, I had never seen this problem on Linux (mainly since I
don't use Linux day to day).

I have, however, seen this problem under OSF1 and other environments
depending on the exact commands.

For example:

; while {true}{true}
[manually hit C-c]
; while {true}{true}
[manually hit C-c]

appears to produce a hung es process for all machines on which I have
es compiled (in all cases, against the GNU readline library).

However, that case is somewhat pathological (and I just avoid it).  On
FreeBSD and Solaris, as long as the predicate is not a built-in
command, terminal interruption appears to work properly multiple times
in a row.  Thus:

; while {sleep 1}{true}
[manually hit C-c]
; while {sleep 1}{true}
[manually hit C-c]
