Module Name:    src

        src/lib/libc/arch/alpha/gen: resumecontext.c
        src/lib/libc/arch/i386/gen: resumecontext.S
        src/lib/libc/arch/x86_64/gen: resumecontext.S

Log Message:
-check for a NULL uc_link before calling setcontext(2); do a real exit(3)
 instead with exit handlers and all that
-If setcontext(2) returns (which it shouldn't), do an _exit(-1) rather
 than relying on a sensible return value to use as exit code. Makes
 it less likely that an ucontext corruption goes unnoticed.
