Subject: C:\cygwin\bin\sh.exe: *** fatal error - couldn't allocate heap,
Win32 error 487

I recently got a new laptop (Thinkpad T60p Centrino Duo), and of course
I installed the current cygwin.  But I frequently get this error:

   2405 [main] ? (66944) C:\cygwin\bin\sh.exe: *** fatal error -
couldn't allocate heap, Win32 error 487, base 0x5D0000, top 0x5E0000,

And by frequently, I mean continuously:  every second command or so, and
frequently in the middle of scripts.  For example, let's try a few
attempts at a find command with -exec...:

Tried it 10 times, no attempt was successful.  Hmm, interesting, there
are two types of the same failure here.

Now, I've searched the mailing lists and this seems to have come up
several times, but I haven't heard anything about a fix.  Help!
