Attaching with strace to the hung process shows "_cygtls::remove: wait 0x0".
Signals sent to the hung process are not delivered (as shown by strace), but a kill -9 will succeed.
Attaching with gdb does show anything that looks promising.
Does anyone have any suggestions that could save me some time, compared to an in-depth study of the Cygwin DLL code in this area?
Max.
