Only to warn users of RHIDE whith many open files.

Debugging within RHIDE a program that opens many files simultaneously, 
under Windows XP. Stopped in a breakpoint in a function called after 
getting error code from open(), I write some code in the editor without 
ending debug session, then hit F2 to save changes. I get a message about 
EMFILE from RHIDE, then something like "want to reload?". I pressed 
Enter without thinking and I lost source file (truncated to 0 bytes). No 
big problem for me this time because no much code lost, but potencially 
destructive. Don't know if it's the same under DOS.

I can't simply increment "FILES=X" limit in \windows\system32\config.nt 
file, because I need to debug the program in limited handles condition 
so I will have to walk around it. I suppose stopping process with 
Ctrl-F2 before saving, there will be no problem.
