removeFile() is silently skipping the operation if the file does not exists (checkf for ENOENT),
but when it is called on a read-only filesystem, the underlying unlink() does not return 
ENOENT, but rather a 'filesystem is read-only' error. So even if the file does not exist, it generates an error that the file cannot be deleted.

…imulation" -> "Debug Next Step"

The "Debug Now" action is useful less often, so a "less
inviting" name was chosen for it. And "Debug Simulation"
was nearly reverted to "Debug Next Event", which it was
called previously, but now that it also breaks when
resuming from a pausePoint(), this is more fitting.
See: 42c2113

The docs didn't even reflect the previous rename of
"Debug Next Event" -> "Debug Simulation".
