Attilio Rao 2e7ecbfbc8 Change gcore in order to get rid of the procfs accesses and use FreeBSD's ... specific sysctls and ptrace interfaces. This change switches a bit gcore POLA that is summarized here: - now gcore can recognize threads within the process and handle dumps on thread-scope - the process to be analyzed will be stopped during its gcore run - gcore may not work with processes which are actively being analyzed by gdb or truss - the ptrace interface may cause syscalls to return EINTR, thus interferring with signals handling within the process Side note: <janitor task> the interface can be further lifted in order to get rid of the very last procfs interfaces remnants and made more suitable for copying with sysctl/ptrace interface </janitor task>.
