I wouldn't be so sure. Process Explorer is a nice tool but it doesn't
always play nice with Cygwin. Specifically, if you click on the Threads
tab of the Properties page of a process, ProcExp attaches its own thread
to the process and this causes the Cygwin process to consume 100% cpu.
You can trivially demonstrate this by clicking on any normal Cygwin
process in ProcExp and then going to the Threads tab in properties. The
cpu usage will shoot to 100%, sometimes shared between the process being
examined and csrss.exe. This does not mean there's anything wrong with
the process, it means that whatever ProcExp is doing is too invasive.
