Subject: Deadlocked cygrunsrv processes with strace message "_cygtls::remove: wait 0x0"

Something about Apache 2 is causing its controlling cygrunsrv service 
process to deadlock within the Cygwin DLL when it attempts to exit.
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.
