/* MIPS is special by having 128 signals.
* All (?) other architectures have at most 64 signals.
* Having 128 signals is problematic because signal nos are 1-based
* and last signal number is then 128.
* This plays havoc with WIFSIGNALED and WCOREDUMP in waitpid status word,
* when process dies from signal 128.
* Linux kernel 3.9 accepts signal 128, with awful results :/
* It is being fixed.
*
* glibc (accidentally?) papers over this issue by declaring _NSIG to be 128,
* not 129 (despite claiming that _NSIG is "biggest signal number + 1"
* in the comment above that definition). We follow suit.
* Note that this results in __SIGRTMAX == 127. It is intended.
