Subject: Make uxsig.o state thread-local.
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=3b548af2381e62d49f524439eb8c0e9bb65cc27b;p=mit-scheme.git

Make uxsig.o state thread-local.

Most of this module's variables are read-only after initialization.
Make blocked_signals and buffer thread-local.
