Subject: Make uxproc.o state thread-local or single-threaded.
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=6a0c5f554fca5288a805ee6b0eebe4d4d3f8a07a;p=mit-scheme.git

Make uxproc.o state thread-local or single-threaded.

Make grabbed_signal_mask pthread-local.  (process_table et al are
already used serially by the runtime system.)
