Hi George,
The "sticky" bit was quite clever. tell the
OS to keep something
memory resident
Was it ever more than a hint? I've not heard of it locking or pinning
an executable to memory.
so you can binary patch the back end without
worrying.
I think it altered the worrying. :-)
If not sticky, ‘chmod -x’ the file, ensure no process is running it from
before the chmod, patch, ‘chmod +x’.
If sticky then ‘chmod -tx’, ensure no process is running it from before
the chmod, ‘chmod +x’, run it and exit to remove any stuck copy,
‘chmod -x’, patch, chmod ‘+tx’.
I may have got the detail wrong but avoiding the unpatched copy
lingering in memory is the aim.
