Perhaps he is :-)

Albert-Jan asks because his package is an interface to an external binary
library, and the location of that library differs according to the platform:

By the way, I don't know that changing directory is a good idea, if you can
avoid it at all. I for one would be *extremely* annoyed if, after calling
what otherwise seems like an innocent library routine, opening files suddenly
started failing (or worse, the wrong file was opened!) because the current
directory was different. Even though you do restore the current directory
when you are done, that makes your routines unsafe for threads.
