It is, I'm the defective link in the chain. :)

You caught me.

Wait, there's a write() syscall? ;)

I should be using an Emacs terminal emulator running zsh, of course,
but I'm still using Sakura and bash. It takes me a while to get the
gumption to upgrade my comfortable tools.

Emacs will tell you that the file has changed and prompt you to update
the buffer. My mistake was far more subtle:

: jmglov@example.com; xemacs Foo/Bar/Baz.pm &
# edit some stuff
: jmglov@example.com; sync-to  # rsyncs the cwd to laurana:`pwd`

# time passes, then I decide to rename the Foo::Bar::Baz module
: jmglov@example.com; git mv Foo/Bar/Baz.pm Foo/Baz.pm

: jmglov@example.com; sync-from  # rsyncs laurana:`pwd` to cwd
# since I didn't add the --delete option to rsync, both Foo/Bar/Baz.pm
and Foo/Baz.pm exist on alhana
# I keep editing Foo/Bar/Baz.pm, forgetting to open a new buffer for
Foo/Baz.pm and close the old buffer

: jmglov@example.com; sync-to  # rsyncs the cwd to laurana:`pwd`
: jmglov@example.com; make clean && make test
# WTF? The changes I made to Foo::Baz are not showing up


My idiocy is a symptom of a crazy workflow that I have not made sane.
I'm taking steps to fix it, but there are historical reasons why I
used to *have* to work this way (or at least, this was the best
option).

Don't blame XEmacs for how I use it. :-P
