I surely agree. I also think I had introduced os_print_error and exactly for 
this purpose, even if I can't recall well.

strerror() is not reentrant so it can't be used, but there is strerror_r.

There is no strsignal_r (using strsignal(3) would clear messages as "Kernel 
mode signal 8"), but I'd suggest to follow the unrecommended but documented 
practice of using sys_siglist[signr].
