Subject: Remove without-interrupts from runtime/geneqht.scm.
X-Git-Tag: mit-scheme-pucked-9.2.12~376^2~43
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=06b315f70d0a43a4f8038057be526cea40bab351;p=mit-scheme.git

Remove without-interrupts from runtime/geneqht.scm.

Serial access to a particular table is still the responsibility of the
user (e.g. SOS procedures?), but the list of all address hash tables
is now a serial population.
