Actually, no.  The simple case is where srchStr is something like:
/Error/

but more complex cases exist like:

!(/Error/ || /Abort/ || /E[0-9]/ || /Warning/B)

(and these are read from several thousand files used in a system that is 
currently written in Perl, so it would be hard to change them all)

I don't think that the eval is the problem here (if it is, that could be a 
problem in itself).  Sure eval will be a bit slower, but it should 
continue to run.  It really seems like the system begins running out of 
some kind of resource as more iterations are run.
