It gets more manageable at -j levels, but there's an underlying bug in the Cygwin DLL's process info management that causes expect to fall into cpu-spinning lockups and cascading process fork collapse syndrome. Until I find time to do a more major rewrite, anyone who wants to do testing on Cygwin could do worse than apply the sticking-plaster patch that I posted at: http://www.mail-archive.com/cygwin-patc...@cygwin.com/msg04677.html and build themselves a locally modified version of the Cygwin DLL that will happily run make check at significant -j levels (I think I tried 12 at most; I've only got a dual-core cpu so it wasn't exactly efficient, but it proved that the patch holds up under substantial load). cheers, DaveK
