    runtime: co-exist with NPTL's pthread_cancel. · c4770b99
    Rowan Worth authored
    NPTL uses SIGRTMIN (signal 32) to effect thread cancellation.
    Go's runtime replaces NPTL's signal handler with its own, and
    ends up aborting if a C library that ends up calling
    pthread_cancel is used.
    
    This patch prevents runtime from replacing NPTL's handler.
    
    Fixes #6997.
