After looking at RemoteString code, I'm not surprised at all by the bug. It was waiting to bite us sooner or later.

in RemoteString, we write the comment with:

string: aString onFileNumber: fileNumber toFile: aFileStream

(use the FileStream in parameter, I suppose this is the unique instance in the system, you'll understand next...)

Then we read back the comment, with... string, where we find:

theFile := (SourceFiles at: sourceFileNumber) readOnlyCopy.

And readOnlyCopy, if we follow the track, will reopen a stream for the same file name, with at the vm level, a different descriptor. So, when the system does a bit of buffering, we are out of sync...
