| === ALL USERS PLEASE NOTE ======================== The garbage collector now works. In addition a new, experimental garbage collection algorithm has been installed. With SI:%DSK-GC-QLX-BITS set to 17, (NOT the default) the old garbage collection algorithm remains in force; when virtual storage is filled, the machine cold boots itself. With SI:%DSK-GC- QLX-BITS set to 23, the new garbage collector is enabled. Unlike most garbage collectors, the new gc starts its mark phase from the mind of the user, rather than from the obarray. This allows the garbage collection of significantly more Qs. As the garbage collector runs, it may ask you something like "Do you remember what SI:RDTBL-TRANS does?", and if you can't give a reasonable answer in thirty seconds, the symbol becomes a candidate for GCing. The variable SI:%GC-QLX-LUSER-TM governs how long the GC waits before timing out the user. | |
| Abstract: This study examined the incidence of neckwear tightness among a group of 94 white-collar working men and the effect of a tight business-shirt collar and tie on the visual performance of 22 male subjects. Of the white-collar men measured, 67% were found to be wearing neckwear that was tighter than their neck circumference. The visual discrimination of the 22 subjects was evaluated using a critical flicker frequency (CFF) test. Results of the CFF test indicated that tight neckwear significantly decreased the visual performance of the subjects and that visual performance did not improve immediately when tight neckwear was removed. -- Langan, L.M. and Watkins, S.M.
