i experience the problem with cygwin 1.5.7-1 and procexp V8.20

when i open up the properties windows of procexp on a cygwin process, 
e.g. a bash, waiting at the prompt, it starts generating a high cpu 
load. the bash still works, but continues to use 60% cpu load even when 
idle...

the problem starts when i select the "threads" tab in procexp, then 
suddenly it starts consuming around 60% cpu in ntdll.dll
the thread that consumes the cpu cycles has listed as "start address":
ntdll.dll!function RtlConvertUiListToApiList+0x1db on WinXP
ntdll+0x1fca5 on an other PC with w2K.
sometimes there are two threads with the same startaddress sharing the 
high load on w2k.

anyone any ideas? what can i do to isolate the problem?

chris
