the error may be caused by trying to do too many accesses to the archive
device to fast. archive devices on its are slow and are often found locked
when one wishes they could be opened. this is more likely to happen on a
fast system than a slow one, since it allows sequential pieces of code that
does this accessing to be reached more quickly. it may not be easily fixable
since the problem is not one in maclisp at all and really shouldn't happen
in the first place... ITS archives are a crock to be avoided wherever possible.
