Strange CGI behaviour in 1.1b5-dev

I am seeing some strange and alarming CGI behaviour in the copy of 1.1b5-dev that I grabbed from the from-cvs directory at about 3:30pm PST today.

For -any- cgi program, hitting reload several times in successionm will produce a server error. There is no predictable frequency of occurance (it does happen freqently however) and no indicated cause other than the usual "premature end of script headers message". Even a simple perl script wich does nothing but output a content-type header and a line of text has this problem. Running it from the command line produces no errors so I am pretty sure that the problem is not the cgi program or interpreter itself.

The official 1.1b4 version does not display this behaviour and the diff I ran on the two source tress shows very little in the way of substantial code changes. Both binaries were compiled and configured in exactly the same way and I am running them on Linux 2.0 (but not the newer libc). Strangely enough, I cannot reproduce this on a box running Linux 1.2.13.

Does anyone have an idea of what might be causing this? There does not seem to be a big difference between the two code trees and it looks like one of the recent changes might be interacting badly with a Linux 2.0 'feature' (the 2.0 kernel is a result of a lot of beta testing and is -assumed- to be stable).

Any ideas or suggestions on how I might track this down? Looking at the error log, you'd think it was just a problem with the script but this is happening for any script, even ones I am 100% sure of. There are no other visible indicators of what might be going wrong.
