The fork() bomb is still a problem with 3.3.4 but it's "benign" under <=3.2.0 because a Ctrl-C reaps the call stack. Something changed significantly between how processes are spawned apparently.
But the CAUSE of the fork() bomb was the combined use of CYGWIN_NOWINPATH=1 and this fragment in my .bashrc
function command_not_found_handle() { cmd.exe /D /C "$@"; }
It now reads:[ -z "${CYGWIN_NOWINPATH+X}" ] && is_exec cmd.exe &&    function command_not_found_handle() { cmd.exe /D /C "$@"; }

sorry, no. Even though I have Admin I am unable to override this. Please note that all previous versions of cygwin1.dll (<3.3.3) are not interfered with. Though if this is indeed Sentinel, it does seem to *sporadically* kill threads launched under strace regardless of cygwin DLL version all the way back to 3.1.7.
