Scsh startup time
I'm referring strictly to the latter: the time it takes for the
program to begin execution. Scsh [Olin's great Scheme shell] takes 30
seconds to start up. Not an LL.
Ack ack ack! It does *not* take 30 seconds to start up. It has been *years*

I don't run a modern Ghz machine. I run exclusively on a two-year-old 300Mhz
notebook. And my /etc scripts and dump/backup scripts and popup-a-window-on-
a-remote-machine scripts are all written in scsh. The single most common
program I use from the shell is "l"; here is its defn:
(let ((flag (if (equal? (getenv "OS") "FreeBSD")
"-CLF" ; Give me a break
(exec-epf (ls ,flag . ,command-line-arguments)))

;;; filenames have spaces or other cruft in them, we still win.
Trust me; I don't sit around tapping my fingers every time I want a quick
Y'all got to help me kill this obsolete but persistent rumour that scsh

that one several years back, too, when Kelsey freed the S48 sources from
So if you have a chance to put a stake through the hear of the
scsh-is-slow-to-start thing, please do.
