Nimble Speed slower with 0.19.0
Running the same nim compile from nimble now takes a lot longer than running the same command at the command line. This just started with the 0.19.0 version.

On the Mac I used the time command to compare the two cases.  In both cases the compiler shows the time and memory usage and these numbers are about the same between versions.  The issue is the actual time as reported by the time command is now way more.

real	0m8.480s  <--- why so big?

I made a simple hello world nimble file and tried the same tests.  In this case nimble is again much shower in 0.19.0 but not as dramatic as my case.

nimble 0.17.0 took 0.3s
nimble 0.18.0 took 0.4s
nimble 0.19.0 took 1.3s  <--- much bigger

time nim c -r hello

nim 0.17.0 took 0.3s
nim 0.18.0 took 0.3s
nim 0.19.0 took 0.3s
