I have testers, but no definite result so far regarding the thread()-version.

But an error-report regarding 1.0.13:

Scanner: UMAX S-6E       V2.0C
SCSI-Card: Adpatec  AHA-1520/1522

When the user does not redirect '1' to a file the scanner works and finishes normal.

When he redirects the image-data to a file image.pnm the scanner starts to work,
but after a while it ends with:

DosDevIOCtl failed. rc= 65314  means 'Interface Busy'

Do you think it makes sense to add 'wait()s' and retry a few times before
giving up or should I suggest to change the card/scanner/cables?

BTW: Sane 1.0.5 works for this user.
