fix missing synchronization of fork with abort
if the multithreaded parent forked while another thread was calling sigaction for SIGABRT or calling abort, the child could inherit a lock state in which future calls to abort will deadlock, or in which the disposition for SIGABRT has already been reset to SIG_DFL. this is nonconforming since abort is AS-safe and permitted to be called concurrently with fork or in the MT-forked child.
