Konstantin Belousov	41d50cd6b7	If process becomes reaper (procctl(PROC_REAP_ACQUIRE)) while already ... having some children, the children' reaper is not reset to the parent. This allows for the situation where reaper has children but not descendands and the too strict asserts in the reap_status() fire. Remove the wrong asserts, add some clarification for the situation to the procctl(2) REAP_STATUS.

Konstantin Belousov	677258f7e7	Add procctl(2) PROC_TRACE_CTL command to enable or disable debugger ... attachment to the process. Note that the command is not intended to be a security measure, rather it is an obfuscation feature, implemented for parity with other operating systems.
