A while ago, I noticed an intermittent crash when running an NT (msvc-7.1) 
build of bjam within cygwin bash where the file used to write out commands 
to would be 0 (because fopen was returning a null file handle, hence the 
crash). IIRC, the errno was EMLINK ("Too many links.").

Rene added a guard against this that terminates with the above error 
message. I was unable to consistently reproduce the error and haven't seen 
it for a while now and am still not sure exactly why the error occurs.

We could try and recover in this situation by waiting for a short while, 
then retrying.

NOTE: The problem file is execnt.c (see revision 1.14).

Bronek: what have you used to build bjam? Are you running through DOS or 
CYGWIN?
